I'm curious to know what it is exactly that the rand() function's algorithim
that it uses to generate numbers is based on?

http://php.net/manual/en/function.mt-rand.php says:

By default, PHP uses the libc random number generator with
the rand() function.

So if you are curious, you can find the C source code for libc and
look for an answer there. Here is the home page for GNU libc:

Good luck searching!
