note 24767 added to ref.session

I'm writing my first PHP application and I?ve tested the saving of the session variables (I use PHP 4.0.6 on SuSE Linux). I've noticed the following: 1. If register_globals is ON, the variables cannot be seen in another page if you don't issue a session_register() after you set the variables. For example the following code: <?php session_start (); $HTTP_SESSION_VARS[ 'testvar'] = "variable transmission test"; $testvar = 'modified'; echo "<a href= \"./secpage.php\">Link</a>"; ?> won't display anything in a second page generated by the code: <?php session_start (); echo "Second Page!"; echo "<br></br> "; if (isset($HTTP_SESSION_VARS[ 'testvar'])) { echo "HTTP_SESSION_VARS: " . $HTTP_SESSION_VARS[ 'testvar']; }; echo "<br></br> "; if (isset($testvar)) { echo "testvar: ". $testvar; }; ?> After I've added the session_register('testvar') line after setting the variables, the following is displayed in the second page: HTTP_SESSION_VARS: modified testvar: modified These is strange because the manual specify not to use session_register if we use $HTTP_SESSION_VARS. 2. If register_globals is off, you don't need to use session_register('testvar') but in the second page displays: HTTP_SESSION_VARS: variable transmission test The conclusion is that if you want your code to work with register_globals set either to On or OFF you must use session_register(). You must also use only $HTTP_SESSION_VARS to set the variable. -- http://www.php.net/manual/en/ref.session.php http://master.php.net/manage/user-notes.php?action=edit+24767 http://master.php.net/manage/user-notes.php?action=delete+24767 http://master.php.net/manage/user-notes.php?action=reject+24767
