note 54216 added to reserved.variables

Note that $_SERVER['QUERY_STRING'] behaves differently under IIS/Apache. In Apache (at least on Windows) it is ALWAYS set - if no query string was specified in the URL, $_SERVER['QUERY_STRING'] is initialised as an empty string. In IIS, if no query string is included in the URL, $_SERVER['QUERY_STRING'] is NOT SET, so trying to access it without checking for its existence will generate notices. ---- Manual Page -- http://www.php.net/manual/en/reserved.variables.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+54216 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+54216&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+54216&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+54216&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+54216&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+54216&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+54216&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+54216&report=yes Search -- http://master.php.net/manage/user-notes.php
