The problem is that when i'm using session_set_save_handler to store session data on an oracle base with php4.0.5, the 'write' function is never called, whereas on a 4.0.4pl1 it works fine ! The 4.0.4pl1 PHP (the good one) is running on a 2000 system, with the same php.ini as below php4.0.5 (the bad one ?) was installed on a linux like this: Configure Command: './configure' '--with-oci8' '--with-apache=../apache_1.3.19' '--enable-track-vars' with this php.ini: [PHP] ;;;;;;;;;;;;;;;;;;; ; About this file ; ;;;;;;;;;;;;;;;;;;; ; This file controls many aspects of PHP's behavior. In order for PHP to ; read it, it must be named 'php.ini'. PHP looks for it in the current ; working directory, in the path designated by the environment variable ; PHPRC, and in the path that was defined in compile time (in that order). ; Under Windows, the compile-time path is the Windows directory. The ; path in which the php.ini file is looked for can be overriden using ; the -c argument in command line mode. ; ; The syntax of the file is extremely simple. Whitespace and Lines ; beginning with a semicolon are silently ignored (as you probably guessed). ; Section headers (e.g. [Foo]) are also silently ignored, even though ; they might mean something in the future. ; ; Directives are specified using the following syntax: ; directive = value ; Directive names are *case sensitive* - foo=bar is different from FOO=bar. ; ; The value can be a string, a number, a PHP constant (e.g. E_ALL or M_PI), one ; of the INI constants (On, Off, True, False, Yes, No and None) or an expression ; (e.g. E_ALL & ~E_NOTICE), or a quoted string ("foo"). ; ; Expressions in the INI file are limited to bitwise operators and parentheses: ; | bitwise OR ; & bitwise AND ; ~ bitwise NOT ; ! boolean NOT ; ; Boolean flags can be turned on using the values 1, On, True or Yes. ; They can be turned off using the values 0, Off, False or No. ; ; An empty string can be denoted by simply not writing anything after the equal ; sign, or by using the None keyword: ; ; foo = ; sets foo to an empty string ; foo = none ; sets foo to an empty string ; foo = "none" ; sets foo to the string 'none' ; ; If you use constants in your value, and these constants belong to a dynamically ; loaded extension (either a PHP extension or a Zend extension), you may only ; use these constants *after* the line that loads the extension. ; ; All the values in the php.ini-dist file correspond to the builtin ; defaults (that is, if no php.ini is used, or if you delete these lines, ; the builtin defaults will be identical). ;;;;;;;;;;;;;;;;;;;; ; Language Options ; ;;;;;;;;;;;;;;;;;;;; engine = On ; Enable the PHP scripting language engine under Apache short_open_tag = On ; allow the <? tag. otherwise, only <?php and <script> tags are recognized. asp_tags = Off ; allow ASP-style <% %> tags precision = 14 ; number of significant digits displayed in floating point numbers y2k_compliance = Off ; whether to be year 2000 compliant (will cause problems with non y2k compliant browsers) output_buffering = Off ; Output buffering allows you to send header lines (including cookies) ; even after you send body content, in the price of slowing PHP's ; output layer a bit. ; You can enable output buffering by in runtime by calling the output ; buffering functions, or enable output buffering for all files ; by setting this directive to On. output_handler = ; You can redirect all of the output of your scripts to a function, ; that can be responsible to process or log it. For example, ; if you set the output_handler to "ob_gzhandler", than output ; will be transparently compressed for browsers that support gzip or ; deflate encoding. Setting an output handler automatically turns on ; output buffering. implicit_flush = Off ; Implicit flush tells PHP to tell the output layer to flush itself ; automatically after every output block. This is equivalent to ; calling the PHP function flush() after each and every call to print() ; or echo() and each and every HTML block. ; Turning this option on has serious performance implications, and ; is generally recommended for debugging purposes only. allow_call_time_pass_reference = On ; whether to enable the ability to force arguments to be ; passed by reference at function-call time. This method ; is deprecated, and is likely to be unsupported in future ; versions of PHP/Zend. The encouraged method of specifying ; which arguments should be passed by reference is in the ; function declaration. You're encouraged to try and ; turn this option Off, and make sure your scripts work ; properly with it, to ensure they will work with future ; versions of the language (you will receive a warning ; each time you use this feature, and the argument will ; be passed by value instead of by reference). ; Safe Mode safe_mode = Off safe_mode_exec_dir = safe_mode_allowed_env_vars = PHP_ ; Setting certain environment variables ; may be a potential security breach. ; This directive contains a comma-delimited ; list of prefixes. In Safe Mode, the ; user may only alter environment ; variables whose names begin with the ; prefixes supplied here. ; By default, users will only be able ; to set environment variables that begin ; with PHP_ (e.g. PHP_FOO=BAR). ; Note: If this directive is empty, PHP ; will let the user modify ANY environment ; variable! safe_mode_protected_env_vars = LD_LIBRARY_PATH ; This directive contains a comma- ; delimited list of environment variables, ; that the end user won't be able to ; change using putenv(). ; These variables will be protected ; even if safe_mode_allowed_env_vars is ; set to allow to change them. disable_functions = ; This directive allows you to disable certain ; functions for security reasons. It receives ; a comma separated list of function names. ; This directive is *NOT* affected by whether ; Safe Mode is turned on or off. ; Colors for Syntax Highlighting mode.

You may want to turn this off if you don't want ; to clutter your scripts' global scope with user data. This makes ; most sense when coupled with track_vars - in which case you can ; access all of the GPC variables through the $HTTP_*_VARS[], ; variables. ; You should do your best to write your scripts so that they do ; not require register_globals to be on; Using form variables ; as globals can easily lead to possible security problems, if ; the code is not very well thought of. register_argc_argv = On ; This directive tells PHP whether to declare the argv&argc ; variables (that would contain the GET information).
