How To Identify The Requested Page In PHP

Question

Is there any easy way to identify the file initially handling the request, ignoring get arguments and handling (at least basic) mappings like / to /index.php<

Answer 1

1. parse_url($_SERVER['REQUEST_URI']) and then pathinfo($path) to get requested filename
2. $_SERVER['PHP_SELF'] to get real filename
3. $_SERVER['SCRIPT_NAME'] to get real filename
