PHP Input Filter: Filter out unwanted PHP / Javascript / HTML tags.

This class can filter input of stray or malicious PHP, Javascript or HTML tags and to prevent cross-site scripting (XSS) attacks. It should be used to filter input supplied by the user, such as an HTML code entered in form fields.

I have tried to make this class as easy as possible to use. You have control over the filter process unlike other alternatives, and can input a string or an entire array to be cleaned (such as $_POST).

** SQL Injection feature has been added.
This recommendation solves the problem.
This recommendation does not solve the problem.

This is the class that I have always used, very easy to configure for what tags and properties to allow and it strips the rest. It does most of the heavy lifting you are looking for including xss filter, except it does not have a bad word filter. I was not able to locate any that combined stripping tags, xss prevention and bad word filter, so you would have to use an additional bad word filter class, there are plenty on here to choose from.
