Description: Generates a random number based on the current hour, day, or month. It does this by seeding the srand with a specific number for each. Usage then remains the same as with any other random. Includes the seeding for the most random number php offers.
function seed_random ($how = 'total')
{
switch ($how)
{
case hour: // Sets A Random Number For The Hour
$time = time();
$today = mktime(0, 0, (int)date("H", $time), (int)date("n", $time),(int)date("j", $time), (int)date("Y", $time));
// N.B. pi makes the script more random so as not to repeat numbers from time to time
srand($today / pi());
break;
case day: // Sets A Random Number For The Day
$time = time();
$today = mktime(0, 0, 0, (int)date("n", $time),(int)date("j", $time), (int)date("Y", $time));
srand($today / pi());
break;
case month: // Sets A Random Number For The Month
$time = time();
$today = mktime(0, 0, 0, 0,(int)date("j", $time), (int)date("Y", $time));
srand($today / pi());
break;
default: // Sets a Truly Random Number Based On The Milisecond
srand((double)microtime()*1000000);
break;
} // Close The Switch Control
} // Close The Function
// Actual Call To Random Remains The Same In All Cases
$some_var = rand (int min, int max);
