a simple css way to add shadow to tables and Divs

This is a PHP and JavaScript Image gallery that I created. There are 2 uses for this.
1.) You can save it as index.php and place in a folder containing images and it will display the images in that folder.
Example:
place index.php in images/folder
http://yoursite.com/images/folder/
This will display all images in that folder

2.) Pass in the path to the folder to display in the url
Example:
Save as imagegallery.php
http://yoursite.com/imagegallery.php?path=images/folde

A quick and simple function to dump a variable (array, object, string, int, etc) out into -formatted output for a web browser.

If the variable is an array or an object, you can have it returned into the another variable for later processing (i.e., through templates or e-mail). Due to lack of free time, if the variable is not an array or an object, it will ignore the $return value and print directly to output.

Future revisions will add the above mentioned functionality.

Generates a tree view within a dropdown select box.

Not really a hack, but rather a workaround for layout problems with IE.
Conditional

Here's a basic function for debugging any kind of PHP variable. It allows for "invisible" or "visible" output--that is output in HTML comments or within visible HTML tags. It also supports customizable "containers" which lets you easily edit the look of the visible and invisible blocks. Examples in code below.

Set a word or phrase in an input field, clear it onfocus

Strip HTML

This is a simple function that resizes and image using the GD add on for PHP.
Just a disclaimer: I know its not perfect, but i figured i would post it because the only other one on here is way confusing to some new PHP developers. Hopefully this one will help you learn how to use GD, and then you can write a better one.

Using styles we can add scrollbars for large table where the space is a constraint
