String Handling in PHP

String Handling in PHP - module H107

The text processing facilities in PHP are wide ranging. Functions are provided for all the common functionality (high-level and low-level) that's required by most users, and for much more besides. We have a saying in PHP Ð "There's a function to do that" Ð and nowhere does it apply more than in text processing.
