note 55475 added to reserved.variables

Warning: $_SERVER['PHP_SELF'] and $_SERVER['SCRIPT_NAME'] may not always be set correctly. Some web hosts implement php as a CGI in such a way that they can turn it on or off for each virtual domain. Several $_SERVER and $_ENV variable values may be incorrect for documents in subdirectory subdomains of these virtual domains. An include-file function or constant, instead of PHP_SELF or some other predefined variable throughout a website, will make it easier to "fix" an entire website in case something changes. <?php function true_url_path() { // Pick the predefined variable that works on your server return $_ENV['SCRIPT_URL']; } ?> Or <?php // Pick the predefined variable that works on your server define("TRUE_URL_PATH", $_ENV['SCRIPT_URL']); ?> ---- Manual Page -- http://www.php.net/manual/en/reserved.variables.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+55475 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+55475&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+55475&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+55475&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+55475&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+55475&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+55475&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+55475&report=yes Search -- http://master.php.net/manage/user-notes.php
