This is a simple credit card validation class that you can check for most issues before you process you form through paypal, authorize.net, or anywhere else. This also uses my Simple Error Class, the error class is required for this.

A very simple error class that can be pretty handy.

This is my MySQL database class that I use for all of my sites. Some included features are:
- Get execution time
- Error reporting (screen and email)
- SQL stats

I made this script to delete any unneeded files from the server that weren't being used by the database. Of course you can expand this a lot more, but I cut it down a little to put it up here.

This is a quick set of overrides for Javascript so that any variable can be passed to PHP in a GET/POST activity. Just call myVar.toPHP();

I use this little set of functions extensively in a little Javascript/PHP RPC handler I wrote. I don't have the reverse function, as I pass JSON back to the browser for the return value.

Note: This lib is not safe for binaries or HTML Elements. The former will come out similar to FTP ASCII breaks, and the latter will cause infinite recursion. If you want to make a speical case for HTML Elements, do so; you could probably just test for parentNode and create a 'safe' object from that. I didn't need it, so I didn't code it.

As for binary safety, at some point between toPHP/escape/post/urldecode/unserialize, the object breaks. Rather than create a huge fix for something I didn't need to do, I put in a quick match/hack. Don't like it? Write the fix yourself.

A proof of concept idea I had for implementing an aspect oriented framework in PHP (yes, I know about http://aophp.net, but it requires a module).

I thought it was neat, so I'm going to share it.

Hope someone likes it.

This function will reverse the affects of register_globals

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

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 PHP class allows you to send SMS to almost every country directly from your website. All you need is an account on www.tm4b.com and PHP 5.

Also required is either cURL or allow_url_fopen enabled in php.ini
