PCRE Tester and Cheat Sheet
Regular Expressions are an extremely powerful tool in any programmers array. Though not always the easiest nuts to crack, so to speak, they are great - when they work correctly. After a rather 'amusing' night of trying to get a complex regular expression to work, I devised a plan.Why not have both a PCRE Tester and Cheat Sheet on the same page? A tool that allows you to input multiple test strings to make things easier, while being able to look at all of the modifiers and syntax at the same time. The PCRE Tester and Cheat Sheet.
In the near future, I'll also be adding the ability to run preg_replace() instead of preg_match(), and a way to load some of the Regular Expressions from my library, as well as save and add your favorites.
