$PHP_SELF, is a Variable in PHP. Its value is the file you are currenty working with.
This could be pretty usefull, if you send a form to the same file. Usung $PHP_SELF you need not write the full path and the filename. You just write:
<? echo $PHP_SELF; ?>
And if the name of the file changes that does not matter. It will send it to itself, nomatter what the filename is, and how often it changed.
