I recently run into the "only Php talk" video and thought that supporting our community member would be a good idea =)

Tweaks found and fixed automatically by Php Inspections (EA Extended) (my pet-project):

• dead code;
• control flow simplifications;
• language level and code style;

I am happy with most of these changes, but I prefer the readability of is_null, so unless there's a good reason I'd like to keep it the way it is.
