Generating Random Numbers with PHP

[Paradine]

Below is a simple function to generate random numbers with PHP:

PHP Code:

<?php
##########################################
# Input: Minimum number, 
#    Maximum number
##################################
function randomNumber($min, $max)
{
    // setup our seed
    srand((float) microtime() * 10000000);
    
    // Generate the number
    $random = rand($min,$max);
    
    // Return the number
    return $random;

}

?>

Usage:

PHP Code:

$random_number = randomNumber(0,50); 


Note: As of PHP 4.2.0, there is no need to seed the random number generator with srand() or mt_srand() as this is now done automatically.

Where is $total_sum declared?

Here:

// Return the number
return $total_sum;

}

?>

Whoops, hehe, my mistake. I've corrected the code now.
