one argument brought forward initially (sorry, can't find the email right now) is the resource management: array_keys() has to create a copy [*] which might be an issue depending on the size of data. - Markus [*] I now about shallow-copy, I'm just trying to cite the initial argument as best as I can :)I currently use foreach (array_keys($array) as $key) { ... } to avoid complains from code analysers on unused var, is it slower?foreach ($iterable as $key => $_) { ... }
