gmp_random - Random number

SYNOPSIS

       GMP gmp_random ([int  $limiter = 20])

DESCRIPTION

	Generate a random number. The number will be between zero and the number of bits per limb multiplied by $limiter. If $limiter is negative,
       negative numbers are generated.

	A limb is an internal GMP mechanism. The number of bits in a limb is not static, and can vary from system to system. Generally, the number
       of bits in a limb is either 16 or 32, but this is not guaranteed.

PARAMETERS

	      o $limiter
		-  The	limiter.  Either a GMP number resource in PHP 5.5 and earlier, a GMP object in PHP 5.6 and later, or a numeric string pro-
		vided that it is possible to convert the latter to a number.

RETURN VALUES

	A random GMP number.

EXAMPLES

       Example #1

	      gmp_random(3) example

	      <?php
	      $rand1 = gmp_random(1); // random number from 0 to 1 * bits per limb
	      $rand2 = gmp_random(2); // random number from 0 to 2 * bits per limb

	      echo gmp_strval($rand1) . "
";
	      echo gmp_strval($rand2) . "
";
	      ?>

	      The above example will output:

	      1915834968
	      8642564075890328087
