More PHP in this blog lately

Recently I work too much with PHP so naturally this blog will go in this direction. I’m trying to be short and at the point, with small but useful snippets of code. I hope that they will help you in some way.
I can’t write long and meaningless chunks of text and when I read developers books I tend to read only the code. In very rare occasions I read some other explanations - they are good when you talk about methodology or algorithm but examples are best when you talk about basics. Actually, this is just an excuse. The main reasons for more code than text in this blog is that I can’t write text.
