I know, but I *want* to seed it. My goal is to have a fixed
pseudorandom sequence for each integer (seed) and I don't want those
sequences to change regarding PHP version.

I wonder whether I can rely on the stability of mt_srand() and

Keep in mind (if you're not already) that mt_rand() doesn't
technically need to be seeded.

Doesn't it also rely on the system clock as well?

No. When I give a fixed seed to mt_srand(), each time I get the same
sequence of mt_rand()s. My question is wheather the actual algorithm
behind these functions is likely to change in the next version of PHP
or not.

why not give us your code and expected results, a few of us can run it
on our various php installs and post back the results.
No other way to find out for sure!
