Because the clients pressure I've to code in PHP. As you may know, I always have bad feelings about PHP, now that feelings are becoming annoying deceptions.

As far four things:

• Can't use class methods as callbacks, if those methods access the $this variable.
• The try/catch exception handling isn't implemented. It almost imposible to handle gently some errors.
• Can't split a class in several files (is not easy maintain big classes).
• Crash in deep inheritance relations.

Why been so sweet Perl or Python, why people insist in write web-apps in a sucky language...

Yeah, I know, because it's easy to code and easy to get something functional quick.
