If you need to access one of the superglobals using a variable variable, you can look it up in $GLOBALS: <?PHP define('FORM_METHOD', 'post'); function getFormVariable( $fieldName, $defaultValue ) { global $FILTER_METHOD; $getpost = $GLOBALS[ '_' . strtoupper(FILTER_METHOD) ]; if ( ! array_key_exists( $fieldName, $getpost ) ) { return $defaultValue; } if ( empty( $getpost[ $fieldName ] ) ) { return $defaultValue; } return $getpost[ $fieldName ]; } echo "<form method=\"".FORM_METHOD."\">\n"; ?> ---- Server IP: 69.147.83.197 Probable Submitter: 93.96.163.94 ---- Manual Page -- http://www.php.net/manual/en/language.variables.variable.php Edit -- https://master.php.net/note/edit/94740 Del: integrated -- https://master.php.net/note/delete/94740/integrated Del: useless -- https://master.php.net/note/delete/94740/useless Del: bad code -- https://master.php.net/note/delete/94740/bad+code Del: spam -- https://master.php.net/note/delete/94740/spam Del: non-english -- https://master.php.net/note/delete/94740/non-english Del: in docs -- https://master.php.net/note/delete/94740/in+docs Del: other reasons-- https://master.php.net/note/delete/94740 Reject -- https://master.php.net/note/reject/94740 Search -- https://master.php.net/manage/user-notes.php
