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

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 ;-)

This function simply splits a file based on the splitter supplied and returns an array with the values. It's pretty much like the file() function. This script could be helpful in section editings.

Over the summer, I worked on a project in which I needed to parse logfiles which were in the following format:

IP|USE|TIME>IP2|USE2|TIME2>

and so on.

When I parsed them to display the log file in a user-friendly fashion, I used the following code:

A simple page hits counter that uses a single cookie to tell the user how many times they have visited the page.
