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).
