! Many random number generators of older libcs have dubious
! or unknown characteristics and are slow. By default, PHP uses the
! libc random number generator with the
! <function>rand()</function> function.
! <function>mt_rand()</function> function is a drop-in
! replacement for this. It uses a random number generator
! with known characteristics, the Mersenne Twister, which
! will produce random numbers that should be suitable for
! cryptographic purposes and is four times faster than
! what the average libc provides. The Homepage of the Mersenne Twister
! can be found at <ulink url="http://www.math.keio.ac.jp/~matumoto/emt.html">http://www.math.keio.ac.jp/~matumoto/emt.html</ulink>,
and an optimized version of the MT source is available from
! <ulink url="http://www.scp.syr.edu/~marc/hawk/twister.html">http://www.scp.syr.edu/~marc/hawk/twister.html</ulink>.
<simpara>
! If called without the optional min,max arguments mt_rand()
! returns a pseudo-random value between 0 and RAND_MAX. If
! you want a random number between 5 and 15 (inclusive), for
! example, use mt_rand(5,15).
<simpara>
Remember to seed the random number generator before use with
<function>mt_srand</function>.
