What is randomness?

Randomness is an event for which there is no causal explanation. This means that the result of a random generator may not be predictable or computable. This, however, contradicts the laws of each computer. In other words, a computer can not produce absolutely random numbers without additional peripherals. In this case we call it pseudo-random numbers. In general, you can philosophize about at which point you can actually speak about randomness.

How are the lottery numbers generated?

Theoretically, three different mechanisms for generating pseudo-random numbers are used in this generator, but two of them are only used to generate the binary string in the background.

Random generator 1 and 2 for binary string

How these random generators work, is explained here in detail.

Random generator 3 for lottery numbers

The previous random number generators produce relatively good random numbers, which, however, can further be improved. The lottery numbers are therefore always generated on server-side with the PHP function random_int(), which generates cryptographically secure pseudo-random numbers:

// Intitialization
for($i = 1; $i <= $Number; $i++) $numbers[] = $i;

// Select all lottery numbers
for($i = 1; $i <= $Subset; $i++) {
	$index 			= random_int(0, count($numbers)-1);
	$lottery_numbers[] 	= $numbers[$index];
	unset($numbers[$index]);				// Delete entry
	$numbers 		= array_values($numbers);	// Reset indexes
