Wed, 27 Sep 2006 09:20:00 -0500

Harry Fuecks is back today on the SitePoint PHP Blog with part two of his "joy of regular expressions" series, continuing on from this previous entry.

He jumps right in, summarizing the first part in a small section before getting back into the examples:

Hunting for .jp(e)gs
Escaping Meta-Characters
Search and Replace
preg_quote()
preg_replace()
Word Boundaries, Word Characters...and everything else
Sub patterns
Spot the XSS Hole
eval() is evil!
preg_replace_callback()

As you can see, it's crammed with just as much infromation as the first part and covers a wide range of topics to help you get more in tune with your inner regular expression guru.

WebProNews: Introduction To Regular Expressions In PHP

Tue, 27 Jun 2006 06:11:59 -0500

Linked to from this new post on the Zend Developer Zone is a handy regular expressions tutorial that any budding PHP developer should definitely check out.

Man I hate REGEX. Not for what it does, it's a powerful weapon. It's part sniper rifle, part bazooka and extremely useful in some situations. As powerful as it is though, it is a pain to write a good REGEX query; especially when you only do it occasionally. Thankfully, Bernard Peh and the gang over at WebProNews have released a primer for REGEX in PHP that makes it a little less painful to work with.

Appropriately titled Introduction To Regular Expressions In PHP, the article starts with a basic REGEX primer. It's sparse on details but it discusses the different types of characters in a REGEX query. Properly formatted, this would be a great little cheat sheet to have handy.

Cal (on the Zend site) mentions that it's a good starting place, but they don't get too deep into the meat of the matter, showing more than just the basics of "this is what this character does". Oh well, I suppose maybe that's being saved for part two...
