I have a file check.php which is called in another php file call.php using file_get_contents('check.php'). I want to maintain a history of files calling check.php by getting the url of requesting files. I have tried $_SERVER['HTTP_REFERER'] but it is not helping. Is there any way I can find out the url of requesting file?

        You could use the debug_backtrace() inside check.php..
$debug = debug_backtrace();
..to display the calling file..
echo $debug[0]['file']);
..and Log this somehwere..
