##http://www.hongkiat.com/blog/regex-web-developers/

Regular expressions are a powerful tool that should be in every developer’s tool belt. They can match against a string of characters based on very complex parameters, which can save you a lot of time when building dynamic websites.

Web developers face different tasks than software developers but many of the same code fundamentals remain. Regular expressions (or regex) do have a steep initial learning curve, but they can be tremendously powerful when used correctly.

The trickiest part is learning the syntax and learning how to write your own regex code from scratch. To save time I’ve organized 30 different regex code snippets that you can incorporate into development projects. And since regex isn’t limited to a single language, you can apply these snippets to anything from JavaScript to PHP or Python.
