Harry Fuecks has gotten busy and posted the third part of his "Joy of Regular Expressions" series over on the SitePoint PHP Blog today.

Following on from the last part, this one is more of an intermission-a round up of regex syntax seen so far and a couple of links following feedback.

He looks at two different topics:

• A "must reads" section of resources for getting the most out of regular expressions
• A comprehensive "cheat sheet" with tips on expression delimiters, literals, pattern modifiers, character classes, quantifiers, assertions, sub-patterns, and working with the blackslash.
