Random but different numbers

[rofl90]

What I want to do is:

 

      $flagIdRand_Correct = rand(0, 999); //update to amount of flags correct answer

        $flagIdRandWrong_a = rand(0, 999); //incorrect answer 1

        $flagIdRandWrong_b = rand(0, 999); //incorrect answer 2

        $flagIdRandWrong_c = rand(0, 999); //incorrect answer 3

 

4 random numbers, they all need to be different..hwo would i do this

I'd do it like this:

 

<?php
$array = range(0,999);
shuffle($array);
$rand = array_slice($array,0,4);
print_r($rand);
?>

Could you run me through what that does, and what it'll return, I presume a $rand[0, 1,2,3]?

<?php
$rands = range(0,999); //Makes an array from 0 to 999
shuffle($rands); //Randomizes the array
$flagIdRand_Correct = rands[0]; //update to amount of flags correct answer
$flagIdRandWrong_a = rands[1]; //incorrect answer 1
$flagIdRandWrong_b = rands[2]; //incorrect answer 2
$flagIdRandWrong_c = rands[3]; //incorrect answer 3
?>
