Test your regular expressions
It's hard to believe that anyone out there can write a complicated regular expression flawlessly on the first attempt. I know it has taken myself a long time to get as good with them as I am now and that's still not very good.
My need to use a regular expression is irregular and everytime I go online to find something that can help me test the expression before using it in code. I've finally found the perfect one with RegExr.
It uses flash and shows the result of your expression as you type. You can also download it as a desktop application using AIR package.

Rules: Paragraphs and linebreaks are automatically created (two or more linebreaks create a paragraph). Linebreaks between code tags remain linebreaks. Block tags cannot be enclosed by inline tags. Red attributes are required and green is optional.
Use "<" and ">" for "<" and ">". Enclosing PHP code in <code> tags will highlight the code (i.e. <code><?php echo 'hello world'; ?></code>).
List of valid tags:
<blockquote title="" cite=""></blockquote><cite cite="" title=""></cite><a href="" title=""></a><strong title=""></strong><em title=""></em><code title=""></code><abbr title=""></abbr><acronym title=""></acronym><ol title=""></ol><ul title=""></ul><li title=""></li>
