How do you generate random numbers?

Computers can generate truly random numbers by observing some outside data, like mouse movements or fan noise, which is not predictable, and creating data from it. This is known as entropy. Other times, they generate “pseudorandom” numbers by using an algorithm so the results appear random, even though they aren't.

What is Mt_rand function in PHP?

The mt_rand() function generates a random integer using the Mersenne Twister algorithm. Tip: This function produces a better random value, and is 4 times faster than rand(). Tip: If you want a random integer between 10 and 100 (inclusive), use mt_rand (10,100).

5. next = ((next * next) / 100 ) % 10000 ;
6. return next ;

How do you generate a non repeating random number in PHP?

php function nonRepeat($min,$max,$count) //prevent function from hanging //due to a request of more values than are possible if($max - $min < $count) return false; $nonrepeatarray = array(); for($i = 0; $i < $count; $i++) $rand = rand($min,$max); //ensure value isn't already in the array //if it is, recalculate ...
