Get the current file name

Hi, due to a current PHP upgrade i am unable to use the following code to get the filename of the page: $s = getenv('SCRIPT_NAME'); I need to get the filename without any avariables attached. For example if the URL is www.mydomain.com/test.php?test=yes using $s = getenv('PHP_SELF'); returns test.php?test=yes how can I return just test.php i.e. the filename on its own Thanks for your help
