PHP Random Number

Turns any string backwards. If you input "Test" it gives out "tseT". Hope it's useful.
The snippet shows how to use it.

This is a faily simple function to validate a URL being passed into your scripts. It will allow for http, https, and ftp. The beginning www. of a URL is optional as well. It will also validate if you have an IP address in place of the domain name. I'm sure this can be improved upon as this is my first attempt at regular expressions but it has worked good for me so far. Please comment or improve if your able.
Thanks!
Thanks!

Similar to Perl's CGI::escapeHTML(), though (because we can!) this adds it as a method to all String objects.

It works with Array types. The example is a simple list of numbers, but the array could contain anything; lists of strings, functions, DOM nodes, whatever. Unfortunately, a lot of things that seem like arrays in the DOM aren't really, so you can't shuffle the images on a page with just document.images.shuffle() all by itself.

"Today in the news, MySQL previews..."
As a "preview" of text, this MySQL select will return the first few words out of a text field in a database. It returns entire words (doesn't cut them off in the middle) and follows the last word with an elipse "..."
In the PHP, assign $CharactersToDisplay to a number - the approximate number of characters desired (or you can hard-code it if you want).
For the example, I also use $TheID as the row identity for the record to display.

This is a class for generating HTML tables. It's kind of rough, but I thought somebody might want to do something with it.

I use this function when passing an array to a function being called from setTimeout();

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 ;-)
