How do I determine the name of a PHP file which is currently executing?

Let's say that I'm executing a PHP program named foo.php. Is there any way that PHP can determine for itself what file is executing? I'm picturing a function that returns "foo.php" (or, even better, "/usr/A1234/foo.php".

I would have thought such a function would already exist in PHP but I can't find anything like this in the PHP manual; maybe I just looked in the wrong place?

 

There are a few server variable you can use including PHP_SELF. Complete list @ http://php.net/manual/en/reserved.variables.server.php

 

Excellent! Thanks PHPMaster!!

 

$_SERVER['PHP_SELF'],$_SERVER['SCRIPT_NAME'] and $SERVER['ORIG_PATH_INFO'] any of one will return you your currently executing file name



here are small program which will explain you in detail that what is use of $_SERVER.

It would be very helpful if you could but such code-blocks inside [ code] [ /code] or [ php] [ /php] wrappers. (Remove the spaces). Makes it a lot more readable.

 

When using .htaccess or other frameworks routes to check what page is being served I use:

echo basename($_SERVER['PHP_SELF']);

PHP:

 

$file = pathinfo(__FILE__, PATHINFO_FILENAME);
