PHP doesn't do enough to encourage building maintainable software. The vast majority of code I've seen "in the wild" grows from a thin, simple layer of logic & SQL queries into an insatiable maintenance monster.

Note: I'm holding back a lot of language nerd rage, so I'm keeping this post very short.

So use a framework. Php's problem is that it doesn't come with an structure. The plus is that you can use any framework that works for you. I use http://www.yiiframework.com and it has shaved 70% off my dev time.

PHP doesn't make it any more difficult to write maintainable software it just makes it easier to not write it.

Take a look at the code, it's well structured.
