3) Yes, but maybe you could state explicitly that mt_rand() "generates
a better random value".
Currently, the first link ("If you require a range larger...") misses
this point and the second link ("See also") is too unspecific.

1) max can be higher than getrandmax(). Random number however will have
only granularity of getrandmax().
2) No.
3) mt_rand() is already linked from the page.

Description:
------------
I'm suggestion to revise this sentence in the docs:
"If you require a range larger than 32768, specifying min and max will
allow you to create a range larger than RAND_MAX, or consider using
mt_rand() instead."
1) As far as I can see, the max parameter cannot be larger than
getrandmax(), otherwise rand() always returns 0. Please mention this
limit! (I'm not sure if this behavior is platform-depended or due to
PHP-internal integer handling, so I cannot suggest a reformulation.)
2) As far as I can see, this limit also applies to mt_rand(), so the
last subsentence "or consider using mt_rand() instead" doesn't make
sense to me.
3) Since mt_rand generates a "better random value", please include an
explicit Note about this fact.
