PHP - Reference to Calling Document?

[Warren Michelsen]

Is there a way to reference the document containing the code being evaluated in PHP?

For example, is there a generic term to be used in place of "index.html" in the example below to indicate the document wherein this filemtime call resides?

instead of:
filemtime("index.html")

filemtime($RefToMe)

Any such thing exist?

I don't follow what you are trying to reference. -scout

Does this do what you want?

<?php echo $_SERVER['PHP_SELF']; ?>
