That wasn't the question, and your claim doesn't have to be true. perl (lowercase) doesn't have its own random number generator. When Perl is build, it probes the OS to see what random number generators its C library has available. It picks what it thinks is best.

But if all your OS has to offer is a 16-bit random number generator, you're not at all better off than in PHP. Perl is fully at the mercy of the OS; while the article you point at seems to state PHP programmers have the option of using either a function from the OS, or a PHP supplied one.

BTW, your href is broken.
