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.

A simple page hits counter that uses a single cookie to tell the user how many times they have visited the page.

Hide CSS styles from Opera by substituting Latin letter "r" for Unicode character 82 in the media attribute "screen" of the style tag.

Tested in browsers based on Netscape, Mozilla, and Internet Explorer for PC.

Load images more quickly in a web page by having the browser cache them before they are requested by the user.

This script specifies the location of images that share a common folder. It can be used for multiple images and folders.

This method uses less code and is more maintanable than specifying the location of each image individually.
