    How do I escape this with / please?

    <?php /**/ ());?>

    It seems every time I try to find it with grep, it won't find it because of the quantifiers themselves..

    Not yet. Here's what I have: Sorry change to a grep to a find-perl:

    find //dir "*.php"|xargs perl -w -i -p -e "s/<?php \/\*\*\/ ());?>//g"

    Then I get error:

    Unmatched ) in regex; marked by <-- HERE in m/<?php /\*\*/ ()) <-- HERE ;?>/ at -e line 1.

    \<\?php \/\*\*\/ \(\)\)\;\?\>

    I'm decent with regular expressions but sometimes it just doesn't work as I think it should. Usually I can correct the problem by escaping characters. As long as the characters you're escaping aren't being eval'd it's harmless to unnecessarily escape them. Like I said "When in doubt..." :D
