note 92011 added to reserved.variables.session

I was having troubles with session variables working in some environments and being seriously flaky in others. I was using $_SESSION as an array. It works properly when I used $_SESSION as pointers to arrays. As an example the following code works in some environments and not others. <?php //Trouble if I treate $form_convert and $_SESSION['form_convert'] as unrelated items $form_convert=array(); if (isset($_SESSION['form_convert'])){ $form_convert=$_SESSION['form_convert']; } } ?> The following works well. <?php if (isset($_SESSION['form_convert'])){ $form_convert = $_SESSION['form_convert']; }else{ $form_convert = array(); $_SESSION['form_convert']=$form_convert; } ?> ---- Server IP: 117.55.229.1 Probable Submitter: 61.9.139.165 ---- Manual Page -- http://www.php.net/manual/en/reserved.variables.session.php Edit -- https://master.php.net/note/edit/92011 Del: integrated -- https://master.php.net/note/delete/92011/integrated Del: useless -- https://master.php.net/note/delete/92011/useless Del: bad code -- https://master.php.net/note/delete/92011/bad+code Del: spam -- https://master.php.net/note/delete/92011/spam Del: non-english -- https://master.php.net/note/delete/92011/non-english Del: in docs -- https://master.php.net/note/delete/92011/in+docs Del: other reasons-- https://master.php.net/note/delete/92011 Reject -- https://master.php.net/note/reject/92011 Search -- https://master.php.net/manage/user-notes.php
