While Loop

This may be a simple question but i'm trying to do a loop while one value doesn't equal the other but for some reason the loop never runs even if the values = each other. Can anyone help me out? :confused:

PHP Code:

---

while ($Number1 != $Number2) {

$Number2 =  intval(rand(100, 999));

$Number1 = $Number2;

} 


---

$Number1 = $Number2; statement false' the loop.

That would be correct. Right? If you want the the loop to execute at least once you use do..while:

PHP Code:

---

do {
 
    $Number2 =  intval(rand(100, 999));

    $Number1 = $Number2;

} while ($Number1 != $Number2);

If initially the $Number1 and $Number2 differ on their values, that would at least execute once.

But if they are the same initially the while loop wouldn't execute. But I don't get it - they will always be the same, so where is the logic in putting a loop? :eek:

If there is no value set for each of the $Number variables before the loop, they would both equal 0, making the while loop not run, because they are equal.
