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.

it give us the position of the mouse. works on IE and Firefox

use:
onclick="posicion_mouse(event)"

Returns the keycode of the key we wrote on a textarea/input. works on IE and Firefox

Returns an array with all the objects with certain class. tested on IE 6 and Firefox 2

Simple set of functions for capturing and manipulating the className member of an HTMLElement

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.

This is a function I created to ease headaches caused by creating and inserting new stuff in an HTML document dynamically. Essentially, it allows you to specify an HTML tag, in its entirety (attributes, styles, event handling, etc), via a single command. You can nest it, so as to create an entire element tree programmatically in a lot less time as with document.createElement.

Don't let the goofy function acronym fool you; this is damned powerful.

First, the function spec:
HTMLElement acne(type[,attributes[,styles[,events[,children[,parent[,document]]]]]]);

Arguments:

String type: type of element to create; same information as the argument of document.createElement
mixed Object attributes: attributes you want the new element to have (ie: href, src)
mixed Object styles: styles for the new element (ie: width, borderLeft)
(function|function Array) Object events: event handlers for the new element
HTMLElement|HTMLElement Array children: elements you want to be in the new element (ie: nesting is possible)
HTMLElement parent: parent node of object
HTMLDocument document: document to create element in

Return value: The newly created/configured element

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.
