I recently tested switching my server from PHP4 to PHP5 (in my hosting account's web panel), and a problem arose: users could no longer log in until I switched back to PHP 4.
Basically, the following line was returning "true" in PHP4 but "false" in PHP5:
Code: Select all
isset($HTTP_COOKIE_VARS['foo'])---
So, what is the difference between cookie usage in PHP4 and PHP5, if any?
