sessions php 5.2.14 Apache windows (vertrigo)

[mauricebis]

Hello,

 

I installed the vertrigo package on Windows XP which runs php 5.12.14. I've a program that uses sessions whose data are stored in a MySql datbase. This program works fine on linux. Almost everything works on windows as well, session_start works, the write handler works. The read handler works and returns the serialized data of the session (I checked this), BUT $_SESSION is empty after session_start?

 

Any help much appreciated. Thanks.

 

Here below are the session configuration parameters and the read handler code.

 

function set_session_parameters() {

/*  ini_set('session.save_path', '/home/piet/sessions/quotes');*/

  session_name('QUOTEID');                        /* call session_name before gc parameters, should be safer*/

  ini_set('session.gc_divisor', '100');

  ini_set('session.gc_maxlifetime', '86400'); /*garbage periodicity for sessions in seconds: 1 day, this applies only to sessions with 'started' status (see _clean_session_quote()).*/

  ini_set('session.gc_probability', '35');      /*this value/divisor(default 100)=probability of launching the garbage collector on session_start(), here probability=3/10*/

  ini_set('session.use_only_cookies', '0');          // don't rely on cookies

  ini_set('session.use_cookies', '0');

  ini_set('url_rewriter.tags',''); //This is in the case the propagation of the sid in the url were enabled (session.use_trans_sid set to 1)  while it should be disabled by default.

  ini_set('session.serialize_handler','php');

  ini_set('session.save_handler','user');

  //use a data base for custom storage of the sessions

  session_set_save_handler('_open_session','_close_session','_read_session','_write_session','_destroy_session_quote','_clean_session_quote');

  }//set_session_parameters

 

function _read_session($id){

  global $dbref;

  $id = mysql_real_escape_string($id);

  $sql = "SELECT data FROM sessions WHERE id = '$id'";

  if (!is_resource($result = @mysql_query($sql, $dbref)))

    throw new Exception("can't read session:" . mysql_error());

  if (mysql_num_rows($result)){

      $record = mysql_fetch_assoc($result);

      return $record['data'];

  }

  return '';

 

}//_read_session

I reply to myself if that can be of any help to others. I didn't manage to get the default php session serializer to work. However, as the XML wddx serializer comes bundled with the windows php version, I explicitly switched to this serializer:

  ini_set('session.serialize_handler', 'wddx');

before starting the session and things work fine.
