生成两个随机数，第一个数小于第二个php

Question

I need to generate two Random numbers using PHP. This is simple but the condition is that the first number should be smaller than second number in value.

So let's say I need to generate lower and upper bounds between 10 and 1000. So I will need two random numbers within this range. First number as lower bound (20 may be) and upper bound higher than that in value so (100 may be).

Thanks Ahmar.

Answer 1

$num1 = rand(20, 999);
$num2 = rand($num1+1, 1000);
