Many random number generators of older libcs have dubious
! or unknown characteristics. 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.
<simpara>
If called without the optional min,max arguments mt_rand()
returns a pseudo-random value between 0 and RAND_MAX. If

<function>mt_rand()</function> function is a drop-in

will produce random numbers that should be suitable for
