What the PHP? Assigning Link Colors by Day

(If you’re not a web developer/designer, you can probably go ahead and tune out, stop reading, and wait for me to post something more pretty and less nerdy. Don’t say I didn’t warn you.)

Help me out here, smart friends… I know enough PHP to get me into trouble, but not really enough to solve the problems I create for myself. 

Here’s the rub:

I use PHP to dynamically switch the hyperlink colors on this site depending on the day. For example, today is Tuesday, so the links are all displayed in a lovely #278FE7 blue. I love PHP’s flexibility for things like this (and other reasons, like the fact that no one can view source and see exactly what’s going on.)

Here’s what I want to do:

I would love to assign a particular link color (or other css style) to each day. For example, instead of it being Tuesday and ALL the links on the site being that lovely #278FE7 blue, I want for ONLY Tuesday’s posts to be that link color. Monday’s posts would have a different link color and so on and so forth.

Hypothetically, you would have seven complimentary link colors displaying at the same time for their respective days, and all of this would be dynamically generated/assigned by PHP from one style sheet. 

(I’m not saying it’s a good idea, or even that I would implement it, though the implications and possibilities for styling-per-day are interesting. More than anything, I just want to know how to do it and haven’t been able to figure it out on my own because I am a programming hack.)
