Hi all,

In considering several possible solutions to a recent task, I found myself considering how to get a php file that includes it's own MD5 hash. I ended up doing something else, but the question stayed with me.

Something along the lines of:

<?php
echo("Hello, my MD5 is [MD5 OF THIS FILE HERE]");
?>

Whatever placeholder you have in the file, the second you take its MD5 and insert it, you've changed it.
