note 12413 deleted from function.array-splice by jimw

i wanted to handle a query-string that way, that a certain variable can be removed from the query-string, while keeping the rest of it. e.g. you can use this to integrate an application into others ( proper API): /** * Proper handling of query-string to make this script * application-independent and easy-integratable. * * @param $index, $addon */ function url($index="page", $addon="" ) { global $HTTP_GET_VARS; foreach($HTTP_GET_VARS as $key => $val ) { $q[$key] = $val; } if(is_array($q )) { // remove $index element from the list unset($q[$index]); // create new query-string foreach($q as $key => $val ) { $str .= "$key=$val&"; } return $str . $addon; } else { return $addon; } }
