srand - Seed the random number generator

SYNOPSIS

       void srand ([int  $seed])

DESCRIPTION

	Seeds the random number generator with $seed or with a random value if no $seed is given.

       Note

	      As  of  PHP  4.2.0,  there is no need to seed the random number generator with srand(3) or mt_srand(3) as this is now done automati-
	      cally.

PARAMETERS

	      o $seed
		- Optional seed value

RETURN VALUES

	No value is returned.

	      function make_seed()
	      {
		list($usec, $sec) = explode(' ', microtime());
		return (float) $sec + ((float) $usec * 100000);
	      }
	      srand(make_seed());
	      $randval = rand();
	      ?>
