Hi. I'm working on a spider, and it needs to preferably empty out the array (or at least make the array smaller as it carries on) ... is there a better option than;

$urls[$_count] = '';

I was thinking about 'pop', but that would mess up my 'foreach'. Is there a good way to remove entries from the array, thus freeing up RAM on the server? Obviously I can't use undef, or can I?

Cheers
