PEAR::Validate function is one of the solutions to web app scripting problems. It provides an array of standard validation routines that allows developers to validate a URL, email addresses, and passwords to prevent XSS exploits. You can also use it to verify International Bank Account Numbers. By applying the validation routines across various PHP projects, you can save a lot of energy and time. In the end, you will have ample time to carry out thorough bug testing.
