In response to yarolan at mail dot ru:
I actually find Duff's Device to be particularly useful in the example put forth by yarolan.
He wrote:
$arr_size=count($arr);
for($i=0;$i<$arr_size;$i++)
{
...
}
If the order of processing doesn't matter, I do this:
$i = count($some_array);
while ($i--):
do_something_to($some_array[$i]);
endwhile;
If it does matter, I like this:
$i = count($some_array);
$some_array = array_reverse($some_array);
while ($i--):
do_something_to($some_array[$i]);
endwhile;
I have no idea if it's faster as I haven't tested it.
Mostly, I just like the way it looks. ;)
