-ADOdb Date Library, part of the ADOdb abstraction library
-Download: http://phplens.com/phpeverywhere/
-
-PHP native date functions use integer timestamps for computations.
-Because of this, dates are restricted to the years 1901-2038 on Unix 
-and 1970-2038 on Windows due to integer overflow for dates beyond 
-those years. This library overcomes these limitations by replacing the 
-native function's signed integers (normally 32-bits) with PHP floating 
-point numbers (normally 64-bits).
-
-Dates from 100 A.D. to 3000 A.D. and later
-have been tested. The minimum is 100 A.D. as <100 will invoke the
-2 => 4 digit year conversion. The maximum is billions of years in the 
-future, but this is a theoretical limit as the computation of that year 
-would take too long with the current implementation of adodb_mktime().
-
-This library replaces native functions as follows:
-
-<pre>	
-	getdate()  with  adodb_getdate()
-	date()     with  adodb_date() 
-	gmdate()   with  adodb_gmdate()
-	mktime()   with  adodb_mktime()
-	gmmktime() with  adodb_gmmktime()
-	strftime() with  adodb_strftime()
-	strftime() with  adodb_gmstrftime()
-</pre>
-	
-The parameters are identical, except that adodb_date() accepts a subset
-of date()'s field formats. Mktime() will convert from local time to GMT, 
-and date() will convert from GMT to local time, but daylight savings is 
-not handled currently.
-
-This library is independant of the rest of ADOdb, and can be used
-as standalone code.
-
-PERFORMANCE
-
-For high speed, this library uses the native date functions where
-possible, and only switches to PHP code when the dates fall outside 
-the 32-bit signed integer range.

-GREGORIAN CORRECTION

-FUNCTION DESCRIPTIONS
-
-
-** FUNCTION adodb_getdate($date=false)
-
-Returns an array containing date information, as getdate(), but supports
-dates greater than 1901 to 2038. The local date/time format is derived from a 
-heuristic the first time adodb_getdate is called. 
-	 
-	 
-** FUNCTION adodb_date($fmt, $timestamp = false)
-
-Convert a timestamp to a formatted local date. If $timestamp is not defined, the
-current timestamp is used. Unlike the function date(), it supports dates
-outside the 1901 to 2038 range.
-
-The format fields that adodb_date supports:
-
-<pre>
-	a - "am" or "pm" 
-	A - "AM" or "PM" 
-	d - day of the month, 2 digits with leading zeros; i.e. "01" to "31" 
-	D - day of the week, textual, 3 letters; e.g. "Fri" 
-	F - month, textual, long; e.g. "January" 
-	g - hour, 12-hour format without leading zeros; i.e. "1" to "12" 
-	G - hour, 24-hour format without leading zeros; i.e. "0" to "23" 
-	h - hour, 12-hour format; i.e. "01" to "12" 
-	H - hour, 24-hour format; i.e. "00" to "23" 
-	i - minutes; i.e. "00" to "59" 
-	j - day of the month without leading zeros; i.e. "1" to "31" 
-	l (lowercase 'L') - day of the week, textual, long; e.g. "Friday"  
-	L - boolean for whether it is a leap year; i.e. "0" or "1" 
-	m - month; i.e. "01" to "12" 
-	M - month, textual, 3 letters; e.g. "Jan" 
-	n - month without leading zeros; i.e. "1" to "12" 
-	O - Difference to Greenwich time in hours; e.g. "+0200" 
-	Q - Quarter, as in 1, 2, 3, 4 
-	r - RFC 2822 formatted date; e.g. "Thu, 21 Dec 2000 16:01:07 +0200" 
-	s - seconds; i.e. "00" to "59" 
-	S - English ordinal suffix for the day of the month, 2 characters; 
-	   			i.e. "st", "nd", "rd" or "th" 
-	t - number of days in the given month; i.e. "28" to "31"
-	T - Timezone setting of this machine; e.g. "EST" or "MDT" 
-	U - seconds since the Unix Epoch (January 1 1970 00:00:00 GMT)  
-	w - day of the week, numeric, i.e. "0" (Sunday) to "6" (Saturday) 
-	Y - year, 4 digits; e.g. "1999" 
-	y - year, 2 digits; e.g. "99" 
-	z - day of the year; i.e. "0" to "365" 
-	Z - timezone offset in seconds (i.e. "-43200" to "43200"). 
-	   			The offset for timezones west of UTC is always negative, 
-				and for those east of UTC is always positive. 
-</pre>
-
-Unsupported:
-<pre>
-	B - Swatch Internet time 
-	I (capital i) - "1" if Daylight Savings Time, "0" otherwise.
-	W - ISO-8601 week number of year, weeks starting on Monday 
-
-</pre>
-
-
-** FUNCTION adodb_date2($fmt, $isoDateString = false)
-Same as adodb_date, but 2nd parameter accepts iso date, eg.
-
-  adodb_date2('d-M-Y H:i','2003-12-25 13:01:34');
-
-  
-** FUNCTION adodb_gmdate($fmt, $timestamp = false)
-
-Convert a timestamp to a formatted GMT date. If $timestamp is not defined, the
-current timestamp is used. Unlike the function date(), it supports dates
-outside the 1901 to 2038 range.
-
-
-** FUNCTION adodb_mktime($hr, $min, $sec[, $month, $day, $year])
-
-Converts a local date to a unix timestamp.  Unlike the function mktime(), it supports
-dates outside the 1901 to 2038 range. All parameters are optional.
-
-
-** FUNCTION adodb_gmmktime($hr, $min, $sec [, $month, $day, $year])
-
-Converts a gmt date to a unix timestamp.  Unlike the function gmmktime(), it supports
-dates outside the 1901 to 2038 range. Differs from gmmktime() in that all parameters
-are currently compulsory.
-
-** FUNCTION adodb_gmstrftime($fmt, $timestamp = false)
-Convert a timestamp to a formatted GMT date.
-
-** FUNCTION adodb_strftime($fmt, $timestamp = false)
-
-Convert a timestamp to a formatted local date. Internally converts $fmt into 
-adodb_date format, then echo result.
-
-For best results, you can define the local date format yourself. Define a global
-variable $ADODB_DATE_LOCALE which is an array, 1st element is date format using
-adodb_date syntax, and 2nd element is the time format, also in adodb_date syntax.
-
-    eg. $ADODB_DATE_LOCALE = array('d/m/Y','H:i:s');
-	
-	Supported format codes:
-
-<pre>
-	%a - abbreviated weekday name according to the current locale 
-	%A - full weekday name according to the current locale 
-	%b - abbreviated month name according to the current locale 
-	%B - full month name according to the current locale 
-	%c - preferred date and time representation for the current locale 
-	%d - day of the month as a decimal number (range 01 to 31) 
-	%D - same as %m/%d/%y 
-	%e - day of the month as a decimal number, a single digit is preceded by a space (range ' 1' to '31') 
-	%h - same as %b
-	%H - hour as a decimal number using a 24-hour clock (range 00 to 23) 
-	%I - hour as a decimal number using a 12-hour clock (range 01 to 12) 
-	%m - month as a decimal number (range 01 to 12) 
-	%M - minute as a decimal number 
-	%n - newline character 
-	%p - either `am' or `pm' according to the given time value, or the corresponding strings for the current locale 
-	%r - time in a.m. and p.m. notation 
-	%R - time in 24 hour notation 
-	%S - second as a decimal number 
-	%t - tab character 
-	%T - current time, equal to %H:%M:%S 
-	%x - preferred date representation for the current locale without the time 
-	%X - preferred time representation for the current locale without the date 
-	%y - year as a decimal number without a century (range 00 to 99) 
-	%Y - year as a decimal number including the century 
-	%Z - time zone or name or abbreviation 
-	%% - a literal `%' character 
-</pre>	
-
-	Unsupported codes:
-<pre>
-	%C - century number (the year divided by 100 and truncated to an integer, range 00 to 99) 
-	%g - like %G, but without the century. 
-	%G - The 4-digit year corresponding to the ISO week number (see %V). 
-	     This has the same format and value as %Y, except that if the ISO week number belongs 
-		 to the previous or next year, that year is used instead. 
-	%j - day of the year as a decimal number (range 001 to 366) 
-	%u - weekday as a decimal number [1,7], with 1 representing Monday 
-	%U - week number of the current year as a decimal number, starting 
-	    with the first Sunday as the first day of the first week 
-	%V - The ISO 8601:1988 week number of the current year as a decimal number, 
-	     range 01 to 53, where week 1 is the first week that has at least 4 days in the 
-		 current year, and with Monday as the first day of the week. (Use %G or %g for 
-		 the year component that corresponds to the week number for the specified timestamp.) 
-	%w - day of the week as a decimal, Sunday being 0 
-	%W - week number of the current year as a decimal number, starting with the 
-	     first Monday as the first day of the first week 
-</pre>

-NOTES
-
-Useful url for generating test timestamps:
-	http://www.4webhelp.net/us/timestamp.php
-
-Possible future optimizations include 
-
-a. Using an algorithm similar to Plauger's in "The Standard C Library" 
-(page 428, xttotm.c _Ttotm() function). Plauger's algorithm will not 
-work outside 32-bit signed range, so i decided not to implement it.
-
-b. Implement daylight savings, which looks awfully complicated, see
-	http://webexhibits.org/daylightsaving/
-
-
-CHANGELOG
-- 19 March 2006 0.24
-Changed strftime() locale detection, because some locales prepend the day of week to the date when %c is used.
-
-- 10 Feb 2006 0.23
-PHP5 compat: when we detect PHP5, the RFC2822 format for gmt 0000hrs is changed from -0000 to +0000. 
-	In PHP4, we will still use -0000 for 100% compat with PHP4.
-
-- 08 Sept 2005 0.22
-In adodb_date2(), $is_gmt not supported properly. Fixed.
-
-- 18 July  2005 0.21
-In PHP 4.3.11, the 'r' format has changed. Leading 0 in day is added. Changed for compat.
-Added support for negative months in adodb_mktime().
-
-- 24 Feb 2005 0.20
-Added limited strftime/gmstrftime support. x10 improvement in performance of adodb_date().
-
-- 21 Dec 2004 0.17
-In adodb_getdate(), the timestamp was accidentally converted to gmt when $is_gmt is false. 
-Also adodb_mktime(0,0,0) did not work properly. Both fixed thx Mauro.
-
-- 17 Nov 2004 0.16
-Removed intval typecast in adodb_mktime() for secs, allowing:
-	 adodb_mktime(0,0,0 + 2236672153,1,1,1934);
-Suggested by Ryan.
-
-- 18 July 2004 0.15
-All params in adodb_mktime were formerly compulsory. Now only the hour, min, secs is compulsory. 
-This brings it more in line with mktime (still not identical).
-
-- 23 June 2004 0.14
-
-Allow you to define your own daylights savings function, adodb_daylight_sv.
-If the function is defined (somewhere in an include), then you can correct for daylights savings.
-
-In this example, we apply daylights savings in June or July, adding one hour. This is extremely
-unrealistic as it does not take into account time-zone, geographic location, current year.
-
-function adodb_daylight_sv(&$arr, $is_gmt)
-{
-	if ($is_gmt) return;
-	$m = $arr['mon'];
-	if ($m == 6 || $m == 7) $arr['hours'] += 1;
-}
-
-This is only called by adodb_date() and not by adodb_mktime(). 
-
-The format of $arr is
-Array ( 
-   [seconds] => 0 
-   [minutes] => 0 
-   [hours] => 0 
-   [mday] => 1      # day of month, eg 1st day of the month
-   [mon] => 2       # month (eg. Feb)
-   [year] => 2102 
-   [yday] => 31     # days in current year
-   [leap] =>        # true if leap year
-   [ndays] => 28    # no of days in current month
-   ) 
-   
-
-- 28 Apr 2004 0.13
-Fixed adodb_date to properly support $is_gmt. Thx to Dimitar Angelov.
-
-- 20 Mar 2004 0.12
-Fixed month calculation error in adodb_date. 2102-June-01 appeared as 2102-May-32.
-
-- 26 Oct 2003 0.11
-Because of daylight savings problems (some systems apply daylight savings to 
-January!!!), changed adodb_get_gmt_diff() to ignore daylight savings.
-
-- 9 Aug 2003 0.10
-Fixed bug with dates after 2038. 
-See http://phplens.com/lens/lensforum/msgs.php?id=6980
-
-- 1 July 2003 0.09
-Added support for Q (Quarter).
-Added adodb_date2(), which accepts ISO date in 2nd param
-
-- 3 March 2003 0.08
-Added support for 'S' adodb_date() format char. Added constant ADODB_ALLOW_NEGATIVE_TS
-if you want PHP to handle negative timestamps between 1901 to 1969.
-
-- 27 Feb 2003 0.07
-All negative numbers handled by adodb now because of RH 7.3+ problems.
-See http://bugs.php.net/bug.php?id=20048&edit=2
-
-- 4 Feb 2003 0.06
-Fixed a typo, 1852 changed to 1582! This means that pre-1852 dates
-are now correctly handled.
-
-- 29 Jan 2003 0.05
-
-Leap year checking differs under Julian calendar (pre 1582). Also
-leap year code optimized by checking for most common case first.
-
-We also handle month overflow correctly in mktime (eg month set to 13).
-
-Day overflow for less than one month's days is supported.
-
-- 28 Jan 2003 0.04
-
-Gregorian correction handled. In PHP5, we might throw an error if 
-mktime uses invalid dates around 5-14 Oct 1582. Released with ADOdb 3.10.
-Added limbo 5-14 Oct 1582 check, when we set to 15 Oct 1582.
-
-- 27 Jan 2003 0.03
-
-Fixed some more month problems due to gmt issues. Added constant ADODB_DATE_VERSION.
-Fixed calculation of days since start of year for <1970. 
-
-- 27 Jan 2003 0.02
-
-Changed _adodb_getdate() to inline leap year checking for better performance.
-Fixed problem with time-zones west of GMT +0000.
-
-- 24 Jan 2003 0.01
-
-First implementation.

-  V4.94 23 Jan 2007  (c) 2006 John Lim (jlim#natsoft.com.my). All rights reserved.
-
-  This is a version of the ADODB driver for DB2.  It uses the 'ibm_db2' PECL extension
-  for PHP (http://pecl.php.net/package/ibm_db2), which in turn requires DB2 V8.2.2 or
-  higher.
-
-  Originally tested with PHP 5.1.1 and Apache 2.0.55 on Windows XP SP2.
-  More recently tested with PHP 5.1.2 and Apache 2.0.55 on Windows XP SP2.
-
-  This file was ported from "adodb-odbc.inc.php" by Larry Menard, "larry.menard#rogers.com".
-  I ripped out what I believed to be a lot of redundant or obsolete code, but there are
-  probably still some remnants of the ODBC support in this file; I'm relying on reviewers
-  of this code to point out any other things that can be removed.

-  Revision 1: (02/25/2005) Updated codebase to include the _inject_bind_options function. This allows
-  users to access the options in the ldap_set_option function appropriately. Most importantly
-  LDAP Version 3 is now supported. See the examples for more information. Also fixed some minor
-  bugs that surfaced when PHP error levels were set high.

-  First cut at the Netezza Driver by Josh Eldridge joshuae74#hotmail.com
- Based on the previous postgres drivers.
- http://www.netezza.com/
- Major Additions/Changes:
-    MetaDatabasesSQL, MetaTablesSQL, MetaColumnsSQL
-    Note: You have to have admin privileges to access the system tables
-    Removed non-working keys code (Netezza has no concept of keys)
-    Fixed the way data types and lengths are returned in MetaColumns()
-    as well as added the default lengths for certain types
-    Updated public variables for Netezza
-    Still need to remove blob functions, as Netezza doesn't suppport blob

-NLS_Date_Format
-Allows you to use a date format other than the Oracle Lite default. When a literal
-character string appears where a date value is expected, the Oracle Lite database
-tests the string to see if it matches the formats of Oracle, SQL-92, or the value
-specified for this parameter in the POLITE.INI file. Setting this parameter also
-defines the default format used in the TO_CHAR or TO_DATE functions when no
-other format string is supplied.
-
-For Oracle the default is dd-mon-yy or dd-mon-yyyy, and for SQL-92 the default is
-yy-mm-dd or yyyy-mm-dd.
-
-Using 'RR' in the format forces two-digit years less than or equal to 49 to be
-interpreted as years in the 21st century (2000–2049), and years over 50 as years in
-the 20th century (1950–1999). Setting the RR format as the default for all two-digit
-year entries allows you to become year-2000 compliant. For example:
-NLS_DATE_FORMAT='RR-MM-DD'
-
-You can also modify the date format using the ALTER SESSION command.

-

-  DB2 data driver. Requires ODBC.
- 
-From phpdb list:
-
-Hi Andrew,
-
-thanks a lot for your help. Today we discovered what
-our real problem was:
-
-After "playing" a little bit with the php-scripts that try
-to connect to the IBM DB2, we set the optional parameter
-Cursortype when calling odbc_pconnect(....).
-
-And the exciting thing: When we set the cursor type
-to SQL_CUR_USE_ODBC Cursor Type, then
-the whole query speed up from 1 till 10 seconds
-to 0.2 till 0.3 seconds for 100 records. Amazing!!!
-
-Therfore, PHP is just almost fast as calling the DB2
-from Servlets using JDBC (don't take too much care
-about the speed at whole: the database was on a
-completely other location, so the whole connection
-was made over a slow network connection).
-
-I hope this helps when other encounter the same
-problem when trying to connect to DB2 from
-PHP.
-
-Kind regards,
-Christian Szardenings
-
-2 Oct 2001
-Mark Newnham has discovered that the SQL_CUR_USE_ODBC is not supported by 
-IBM's DB2 ODBC driver, so this must be a 3rd party ODBC driver.
-
-From the IBM CLI Reference:
-
-SQL_ATTR_ODBC_CURSORS (DB2 CLI v5) 
-This connection attribute is defined by ODBC, but is not supported by DB2
-CLI. Any attempt to set or get this attribute will result in an SQLSTATE of
-HYC00 (Driver not capable). 
-
-A 32-bit option specifying how the Driver Manager uses the ODBC cursor
-library. 
-
-So I guess this means the message [above] was related to using a 3rd party
-odbc driver.
-
-Setting SQL_CUR_USE_ODBC
-========================
-To set SQL_CUR_USE_ODBC for drivers that require it, do this:
-
-$db = NewADOConnection('odbc_db2');
-$db->curMode = SQL_CUR_USE_ODBC;
-$db->Connect($dsn, $userid, $pwd);
-
-
-
-USING CLI INTERFACE
-===================
-
-I have had reports that the $host and $database params have to be reversed in 
-Connect() when using the CLI interface. From Halmai Csongor csongor.halmai#nexum.hu:
-
-> The symptom is that if I change the database engine from postgres or any other to DB2 then the following
-> connection command becomes wrong despite being described this version to be correct in the docs. 
->
-> $connection_object->Connect( $DATABASE_HOST, $DATABASE_AUTH_USER_NAME, $DATABASE_AUTH_PASSWORD, $DATABASE_NAME )
->
-> In case of DB2 I had to swap the first and last arguments in order to connect properly. 
-
-
-System Error 5
-==============
-IF you get a System Error 5 when trying to Connect/Load, it could be a permission problem. Give the user connecting
-to DB2 full rights to the DB2 SQLLIB directory, and place the user in the DBUSERS group.

-  21.02.2002 - Wade Johnson wade@wadejohnson.de
-			   Extended ODBC class for Sybase SQLAnywhere.
-   1) Added support to retrieve the last row insert ID on tables with
-	  primary key column using autoincrement function.
-
-   2) Added blob support.  Usage:
-		 a) create blob variable on db server:
-
-		$dbconn->create_blobvar($blobVarName);
-
-	  b) load blob var from file.  $filename must be complete path
-
-	  $dbcon->load_blobvar_from_file($blobVarName, $filename);
-
-	  c) Use the $blobVarName in SQL insert or update statement in the values
-	  clause:
-
-		$recordSet = $dbconn->Execute('INSERT INTO tabname (idcol, blobcol) '
-		.
-	   'VALUES (\'test\', ' . $blobVarName . ')');
-
-	 instead of loading blob from a file, you can also load from 
-	  an unformatted (raw) blob variable:
-	  $dbcon->load_blobvar_from_var($blobVarName, $varName);
-
-	  d) drop blob variable on db server to free up resources:
-	  $dbconn->drop_blobvar($blobVarName);

-  Set tabs to 4 for best viewing.
-  
-  Latest version of ADODB is available at http://php.weblogs.com/adodb
-  ======================================================================
-  
- This file provides PHP4 session management using the ADODB database
-wrapper library.
- 
- Example
- =======
- 
-	include('adodb.inc.php');
-	#---------------------------------#
-	include('adodb-cryptsession.php'); 
-	#---------------------------------#
-	session_start();
-	session_register('AVAR');
-	$_SESSION['AVAR'] += 1;
-	print "
--- \$_SESSION['AVAR']={$_SESSION['AVAR']}</p>";
-
- 
- Installation
- ============
- 1. Create a new database in MySQL or Access "sessions" like
-so:
- 
-  create table sessions (
-	   SESSKEY char(32) not null,
-	   EXPIRY int(11) unsigned not null,
-	   EXPIREREF varchar(64),
-	   DATA CLOB,
-	  primary key (sesskey)
-  );
-  
-  2. Then define the following parameters. You can either modify
-     this file, or define them before this file is included:
-	 
-  	$ADODB_SESSION_DRIVER='database driver, eg. mysql or ibase';
-	$ADODB_SESSION_CONNECT='server to connect to';
-	$ADODB_SESSION_USER ='user';
-	$ADODB_SESSION_PWD ='password';
-	$ADODB_SESSION_DB ='database';
-	$ADODB_SESSION_TBL = 'sessions'
-	
-  3. Recommended is PHP 4.0.2 or later. There are documented
-session bugs in earlier versions of PHP.

-  

-  Latest version of ADODB is available at http://php.weblogs.com/adodb

-  ======================================================================

-  

- This file provides PHP4 session management using the ADODB database

- wrapper library, using Oracle CLOB's to store data. Contributed by achim.gosse@ddd.de.

-

- Example

- =======

- 

-	include('adodb.inc.php');

-	include('adodb-session.php');

-	session_start();

-	session_register('AVAR');

-	$_SESSION['AVAR'] += 1;

-	print "

--- \$_SESSION['AVAR']={$_SESSION['AVAR']}</p>";

-	

-To force non-persistent connections, call adodb_session_open first before session_start():

-

-	include('adodb.inc.php');

-	include('adodb-session.php');

-	adodb_session_open(false,false,false);

-	session_start();

-	session_register('AVAR');

-	$_SESSION['AVAR'] += 1;

-	print "

--- \$_SESSION['AVAR']={$_SESSION['AVAR']}</p>";

-

- 

- Installation

- ============

- 1. Create this table in your database (syntax might vary depending on your db):

- 

-  create table sessions (

-	   SESSKEY char(32) not null,

-	   EXPIRY int(11) unsigned not null,

-	   EXPIREREF varchar(64),

-	   DATA CLOB,

-	  primary key (sesskey)

-  );

-

-

-  2. Then define the following parameters in this file:

-  	$ADODB_SESSION_DRIVER='database driver, eg. mysql or ibase';

-	$ADODB_SESSION_CONNECT='server to connect to';

-	$ADODB_SESSION_USER ='user';

-	$ADODB_SESSION_PWD ='password';

-	$ADODB_SESSION_DB ='database';

-	$ADODB_SESSION_TBL = 'sessions'

-	$ADODB_SESSION_USE_LOBS = false; (or, if you wanna use CLOBS (= 'CLOB') or ( = 'BLOB')

-	

-  3. Recommended is PHP 4.1.0 or later. There are documented

-	 session bugs in earlier versions of PHP.

-

-  4. If you want to receive notifications when a session expires, then

-  	 you can tag a session with an EXPIREREF, and before the session

-	 record is deleted, we can call a function that will pass the EXPIREREF

-	 as the first parameter, and the session key as the second parameter.

-	 

-	 To do this, define a notification function, say NotifyFn:

-	 

-	 	function NotifyFn($expireref, $sesskey)

-	 	{

-	 	}

-	 

-	 Then you need to define a global variable $ADODB_SESSION_EXPIRE_NOTIFY.

-	 This is an array with 2 elements, the first being the name of the variable

-	 you would like to store in the EXPIREREF field, and the 2nd is the 

-	 notification function's name.

-	 

-	 In this example, we want to be notified when a user's session 

-	 has expired, so we store the user id in the global variable $USERID, 

-	 store this value in the EXPIREREF field:

-	 

-	 	$ADODB_SESSION_EXPIRE_NOTIFY = array('USERID','NotifyFn');

-		

-	Then when the NotifyFn is called, we are passed the $USERID as the first

-	parameter, eg. NotifyFn($userid, $sesskey).

-To force non-persistent connections, call adodb_session_open first before session_start():

-

-	include('adodb.inc.php');

-	include('adodb-session.php');

-	adodb_sess_open(false,false,false);

-	session_start();

-	session_register('AVAR');

-	$_SESSION['AVAR'] += 1;

-	print "

--- \$_SESSION['AVAR']={$_SESSION['AVAR']}</p>";

- 

- Installation

- ============

- 1. Create this table in your database (syntax might vary depending on your db):

- 

-  create table sessions (

-	   SESSKEY char(32) not null,

-	   EXPIRY int(11) unsigned not null,

-	   EXPIREREF varchar(64),

-	   DATA text not null,

-	  primary key (sesskey)

-  );

-  

-  For oracle:

-    create table sessions (

-	   SESSKEY char(32) not null,

-	   EXPIRY DECIMAL(16)  not null,

-	   EXPIREREF varchar(64),

-	   DATA varchar(4000) not null,

-	  primary key (sesskey)

-  );

-

-

-  2. Then define the following parameters. You can either modify

-     this file, or define them before this file is included:

-	 

-  	$ADODB_SESSION_DRIVER='database driver, eg. mysql or ibase';

-	$ADODB_SESSION_CONNECT='server to connect to';

-	$ADODB_SESSION_USER ='user';

-	$ADODB_SESSION_PWD ='password';

-	$ADODB_SESSION_DB ='database';

-	$ADODB_SESSION_TBL = 'sessions'

-	

-  3. Recommended is PHP 4.1.0 or later. There are documented

-	 session bugs in earlier versions of PHP.

-

-  4. If you want to receive notifications when a session expires, then

-  	 you can tag a session with an EXPIREREF, and before the session

-	 record is deleted, we can call a function that will pass the EXPIREREF

-	 as the first parameter, and the session key as the second parameter.

-	 

-	 To do this, define a notification function, say NotifyFn:

-	 

-	 	function NotifyFn($expireref, $sesskey)

-	 	{

-	 	}

-	 

-	 Then you need to define a global variable $ADODB_SESSION_EXPIRE_NOTIFY.

-	 This is an array with 2 elements, the first being the name of the variable

-	 you would like to store in the EXPIREREF field, and the 2nd is the 

-	 notification function's name.

-	 

-	 In this example, we want to be notified when a user's session 

-	 has expired, so we store the user id in the global variable $USERID, 

-	 store this value in the EXPIREREF field:

-	 

-	 	$ADODB_SESSION_EXPIRE_NOTIFY = array('USERID','NotifyFn');

-		

-	Then when the NotifyFn is called, we are passed the $USERID as the first

-	parameter, eg. NotifyFn($userid, $sesskey).
