Heya, PC.

Upgrading from PHP 4 to 5 is a pretty BIG change; in some ways, your
app will run more efficiently, but more likely, PHP is running in
emulation mode. For example, classes written for PHP 4 are less
efficient than PHP 5 classes.

To complete your migration, you'll need to rewrite your app for PHP 5:
