The real problem with PHP
Yes, let me introduce you to the professional PHP programmer. You see, PHP is like a handgun. On its own, it is simply an inanimate tool that has no moral leaning. In the hands of a responsible citizen, it can be used to the benefit of society. But in the hands of someone who is untrained or mentally unstable, it can be used to commit horrible atrocities.
Whenever there’s such a tragedy, other developers are quick to blame PHP. If PHP were illegal, then Yahoo would never have happened. If we regulated PHP tightly, then there would be no Digg. Now, it’s not fair to say that the world would be better off without PHP, but its community could certainly use less encouragement, which is why Azure’s support for PHP worries me.
This has been one of my primary criticisms of PHP from day one, aside from some elements of the language that don't make sense. PHP can be used to create elegant and fast web applications, but only in the hands of competent programmers. It is way too easy to easy to create horrible spaghetti code in PHP. Even in the hands of said competent programmers, maintaining PHP code others have written I think is also more difficult than it needs to be. Then again I've heard people use the exact same observations to claim the language is more flexible; each to their own.
In a way I make up for a lack of time by using high level languages like Ruby and Python because more than PHP (or Perl) they force you to do things "more correctly", Python moreso.
