When you bring up the editor on this site, there's a button up there that says php. If you click it, you get tags that look like this: [ php ] but without the spaces I added (so you could see it.)
They cause your code to be color coded, which helps you find these things.
Also, if you're running apache, you can turn on the phps handler function with the line:
AddType application/x-httpd-php-source .phps
in httpd.conf
then, you can do:
ln -s sourcefile.php sourcefile.phps
and when you view the phps file in your web browser (served through apache) it will be nicely color coded as well.
Oh yeah, and you're welcome... Welcome to the board.
