These are things in PHP which make me sad. They are real, objective issues which I have personally encountered in my normal day-to-day activites. Nothing on this site should be taken to be the view of my employer or is related to my employer in any way.

The page is split up into several different sections including:

• Lexer/Parser Issues
• Inconsistency
• Anti-functional Design
• Arbitrary Restrictions

Each of the for most of the things on the list, he's linked to a page showing some example code of the complaint and how significant of an impact it could have on your code. He's also set up a discussion board for those that want to talk about these issues further.
