Looking for a coding support program

[h8ids]

Been utilizing such coding commands as echo, alert and write for troubleshooting.

Wondering if there is a program that can monitor the sequence of coding events as a page loads.

OR

Does anyone know of a site which explains the sequence of processing events when it comes to using HTML, CSS, DHTML, PHP and Javascript.

I realize PHP is first, but the client side codes still are a bit of a mystery.

I'm fairly sure HTML, CSS and Javascript are read (and processed, if required) in the order in which they appear in the source code.

The only exception to this that I'm aware of is HTML tables, I believe when the browser encounters a table it reads the row and column structure first before filling in the contents of the table.

DHTML by the way stands for 'dynamic HTML' and is just a name for a combination of Javascript, HTML and CSS; it's not a unique entity in it's own right.
