Open a File For Input

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

Customizable recursive directory scanner.

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.

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

Here's a little snippet I got from SitePoint that I now use all the time. Add the code below to the start of each script.

Basically, what this does is checks to see if magic_quotes_gpc() is enabled on the server, and if it is, then it gets rid of all the slashes that magic_quotes_gpc() adds to input from $_GET, $_POST and $_COOKIES globals.

It's a good snippet to use, because it negates the bad programming practices that having magic_quotes_gpc() lets you get away with, and means that you don't really on PHP to validate your input; you get to do it all yourself ;-)

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