You're doing it wrong then (I think).

1. You should always initialize your loop counters.

i.e.

$x = 0;

while($x < 100)
{
        $x++;
}

2. Don't use the same counter name in all your loops.

This is bad:

for($x=0;$x<100;$x++)
{
        for($x=0;$x<100;$x++)
        {
                echo "i'm going to go on forever!!";
        }
}

This Is Good(tm):

for($x=0;$x<100;$x++)
{
        for($x=0;$x<100;$x++)
        {
                echo "Me happy now!!";
        }
}



Does that help?

Chris.
