Today I found a great PHP tutorial series called “Diving into PHP”. It is made by Jeffrey Way from nettuts and it has 15 episodes till now. It starts from scrach and slowly builds up to advanced topics that is why it is great for PHP beginers and for advanced users.

Regular expressions? What they are? How do they help us? How to use them? This is what you’ll learn from this series of tutorials. Regular expressions can help us very much if we have to find different portions of string in a bigger context. If we have a pattern for those string than we can make a regular expression that we will use in our search.
