A little function that does some basic checking for data input by a user. Should get rid of code injection ;-)

This simple function will check if a url is valid (going by parse_url()) and if it's 'online' - by seeing if it returns a 302, 301, or 200 status code.

This small snippet will not allow _POST requests from a 'foreign' domain. It relies on the HTTP_REFERER variable.

This function will reverse the affects of register_globals

This is a simple PHP script that will show whether a certain port/socket of a certain computer is currently open/active.

This multiple-use PHP script will randomly generate content based on a randomly generated number.

Enforce loadig fresh script code for the external javascript files. Compatible with HTTP 1.0.

Make External Links Open in New Window

This detects screen resolution using javascript and makes it available to php by way of cookies.
