This isn't really a question...

But it is related to PHP regex and all that.

This tool is really amazing. I don't use it to replace my own regex, but it's very, very helpful in learning the syntax and construction of PCRE. You can generate code for different languages;

perl, php, python, java, javascript, coldfusion, c, c++, ruby, vb, vbscript, j#, c#, c++.net, vb.net, to be exact.

Hope this helps someone, and not by just getting the job done, but helping them learn how to use regular expressions.

P.S Sorry if this has been shared already.
