Getting the name of file in PHP

Question

How can I get the name of a file in in PHP? What I want to do is have a function take a string of a filename and then do some stuff if it's actually on the page.

function onThisPageFunction(fileNameFromFunction)  
{  
  if(onThisPage == fileNameFromFunction)  
  {  
    do stuff  
  }  
}

There are two variables that will give you file names.

eg: you call /test/test1.php as the url and test1.php includes test2.php.

__FILE__ will give you the current file of the executing code, in this case it will return "test2.php"

$_SERVER['PHP_SELF'] will give you the full url of the original call, in this case "/test/test1.php"

Note that you can use the basename() function to get just the filename from a path.
