note 52474 added to ref.session

Here is a script a made to initialize global variables when both GET and SESSION variables are defined. This is common when SESSION variables retain information that is changed by a GET value. For example, when a user selects a style, the url is tagged with ?style=STYLETYPEONE, so $_SESSION['style'] should be set to the get. However, if no get is set then the session variable should remain what it was. If the session variable isnt set either, then it should be set to the default value of the variable. Here is the code: # a session helpful thing, start a session, with default session values # if get for that var is set set the var to th get otherwise use session session_start(); $ses_vars = array('var1'=>var1defaultvalue, # list of passed get vars 'var2'=>var2defaultvalue, 'var3'=>var3defaultvalue); foreach ($ses_vars as $var=>$default) { if (!isset($_SESSION[$var])) $_SESSION[$var] = $default; if (!isset($_GET[$var])) ${$var} = $_SESSION[$var]; else ${$var} = $_GET[$var]; } -Frank http://entelekheia.net ---- Manual Page -- http://www.php.net/manual/en/ref.session.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+52474 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+52474&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+52474&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+52474&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+52474&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+52474&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+52474&report=yes Search -- http://master.php.net/manage/user-notes.php
