Lifetime of Filehandler within Session

Hi PHP cracks, I need your help with my litte problem here: I need to setup and maintain a tcp-socket connection within a PHP session, because the service on the other side keeps track of the client's state and decides at runtine which html-page is to be displayed as a result of the users form-entries and also manages the database-IO. given the code snippet below, I discovered that variable $dynamx_result is set correcty when page2.php is reached while $jds_connection is 0 (in scope of page1.php it is something like resource#1) ! Is there something special when filehandles are registed within sessions ? Where is the difference ? Any help would be great. Dirk ---------------------------------------------------------------------------- ------------------------------------------------------------------------- page1.php: ======== require("lib.php"); $jds_connection = -1; $dynamx_result = "@<CMD> <session> <URL>"; $status = dynamx_LogIn($username, $password); // Login ok ? // start new session, register vars and redirect to page given by $dynamx_result if ($status==1) { session_start(); session_register("jds_connection"); session_register("dynamx_result"); // redirect to page2.php header("Location: $dynamx_redirect?".session_name()."=".session_id()); exit; } ... page2.php: ======== <?php session_register("jds_connection"); session_register("dynamx_result"); ?> <title>Beispielformular - <?php echo $jds_connection?> - <?php echo $dynamx_result?></title> lib.php ======= function LogIn( $a_username, $a_password) { global $jds_connection; global $dynamx_result; $jds_connection = fsockopen(JDS_SERVER_HOST,JDS_SERVER_PORT); ... // do some communication here and set $dynamx_result accordingly }
