The following script is a single interface for pre-validating any HTML form. It lets you validate your form data the way you want, while handling the rudimentary tasks itself.
1) Change just one variable to make it work with $_GET or $_POST or $_REQUEST.
2) Name which elements are 'required' all at once in a hidden HTML text input.
3) Easily provide field descriptions in hidden HTML text inputs that you can use to print error statements.
4) Call a single function to print out error statements that you can easily style with CSS.
5) It automatically checks if fields marked 'required' have been filled out.
Most of the pre-validation code is from PHP 5: Unleashed by Sams Publishing. I found it extremely useful for a recent project. Sharing it here, I removed some unnecessary functions, and tried to simplify some points.
All the comments are my own; hopefully I provided more than enough explanation.

Below is a function written in ColdFusion MX that will return an array containing all matches found when running a regex against a particular string. Each array item is a structure with the match, the starting character position, the ending character position, and an array of any
sub-pattern captures.
