If your various user classes inherit from a parent user class, then I recommend you use the same inheritance structure for your test case classes.

Looking for things like sequential scans can be somewhat useful, but the reality is in the numbers... except when the numbers are just estimates!

Depends on the source control system you use. For example, for subversion and cvs your files can reside in a remote location, but you always check out your own copy of them locally.

I am a Prototype person, but I've used jQuery a bit. Honestly I don't there is much between the two that you can use as a 'selling point'. The YUI on the other hand is pretty bloated. I would never use it on any commercial grade application.

You don't need a DTD for DOMDocument to parse custom XML. Just use `DOMDocument->load()`, and as long as the XML is well-formed, it can read it.
Once you get the files to be well-formed, that's when you can start looking at XML parsers, before that you're S.O.L. Lok Alejo said, you could look at [HTML TIDY](h... |

If every method is just a static call straight to the data source, then the "Posts" class is really a Factory. You could certainly put the static methods in "Posts" into the "Post" class (this is how CSLA works), but they are still factory methods.

If only the CSS equivalent was as expedient in setting up a "table-like" layout, then I would love to use CSS.

It's easy.
Think your webpage as a real page on paper.
You should use tables on webpage only when you would draw a table on your paper.
Another tip is to use table only with border > 0.
This way, you use tables only when you **mean** you want a table (and not for layout). |

As suggested, you should use
seq -f 'frame-%g.jpg' 1 4 number-of-frames

The problem is that "event based programming" links far too much logic to the events.
