I have an array that is initialised with many keys and all values set to
NULL. I'd like to be able to test these values later to see if any of
them have been set. I tried:
if (!empty(array_values($the_array)))
but that's not allowed, so:
$array_check = array_values($the_array);
if (!empty($array_check))
but that doesn't work, either, because, though the values of *that*
array are all NULL, the array itself is not empty.
Now, i know that i can simply set some $var to TRUE whenever one of the
array vales is set. And i can also just test them in a loop. But my
curiosity has gotten the better of me.
