Loop Help

ppohlmann

Hello all,

I have a problem and starting to loose my hair over that..

$a=randomgenerator(); 
$b=randomgenerator();

do
{
$a=randomgenerator();
$b=randomgenerator();

} while($a==$b)

The goal is that $a and $b from the random number generator are never the same.
Any other way to do that ?

Thanks
Peter

What's wrong with the way you're doing it now? The loop will hardly ever iterate more than once (if ever), depending on the random number generator used (the MT generator, for example).

Looks like that the loop is looping and never stops

So "randomgenerator()" is something you've written, and not a stand-in for [man]rand[/man] or [man]mt_rand[/man]? Because it sounds like that's where the problem is.

(Incidentally, why do you run it twice then immediately throw those first two values away when you start the loop?)

function randomgenerator()
{
$pick = (mt_rand(12, 48));
return $pick;
}

The 2 values should not be the same.

alright.. found the problen .. as usual own stupidity .. $$pick instead of $pick in the function.
Sorry for bothering you .. and thanks for the help.

Probably i should replace my glasses..
