Re: [PHP-DEV] Variable Scope

[LingWitt]

Since the inner loop declares $i again, it should mask the outer loop's 
$i as per other languages. Besides being useful, it makes more sense. 
Otherwise, the declaratory statement in the second loop is completely 
meaningless.

? This example works perfectly fine. What's your problem here? What do
you mean with "mask the outer loop"? Of course if you modify $i INSIDE
the loop the outer one is affected.

Variable scope is mediocre at best. For instances:

$array = array(1, 2, 3, 4, 5);

for ($i = 0; $i < 5; $i++)
{
        $num = $array[$i];
        echo $num;
        for ($i = 0; $i < 5; $i++)
        {
                echo $num * $i;
        }
}
The inner loop $i doesn't mask the outer loop $i.
Thus, the whole things gets screwed up.
