Mastering Regular Expressions in PHP
(Page 4 out of 4)Regular expressions are actually one of the most powerful tools in PHP, or any other language for that matter (you can use it in your mod_rewrite rules as well!). There is so much you can do with regex, and we've only scratched the surface in this tutorial with some very basic examples.
If you really want to dig into regex I suggest you search on Google for more tutorials, and try to learn the regex syntax. It isn't easy, and there's quite a steep learning curve (in my opinion), but the best way to learn is to go through a lot of examples, and try to translate them in plain English. It really helps you learn the syntax.
In the future I will dedicate a complete article to strictly examples, including more advanced ones, without any explanation. But for now, I can only give you links to other tutorials:
