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.

This code allows you to set the "opcity" style attribute on a element without affecting it's content.

Just call the function for a specific element or to all elements of a given classname after the document loads.

Examples and advanced usage here...

These are some prototype methods to handle class names in html elements. As you all should know, a html element can have more than one class name.

This is part of my dom handling toolkit. Check it out and use it at will.

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

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

This function is useful in helping to deter spam bots by obfuscating things such as e-mail addresses and URLs that are displayed on a web page. While it's not 100% fool proof, it does offer some protection.

Example:
$email = html_entitize('foo@baz.org');
/*
Outputs foo@baz.com
*/

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.
