String Comparison in PHP
Scrip Reviewed by Vicky, 2009-06-03

Love the little script. I use it everywhere, but I noticed that it didn't work with one hosting company (different config I guess). Anyway, I changed the following string comparison:

if(md5(strtoupper($_POST['code'])) == $_SESSION['__img_code__'])

to:

if (strcmp( md5(strtoupper($_POST['code'])), $_SESSION['__img_code__'] ) )


and it works beautitfully. Thanks heaps.

Regards

Vicky
