See www.php.net/array_pop.

Description:

I get a "PHP Strict Standards: Only variables should be passed by reference
in"
error where there should be none.

echo array_pop(array_keys(array("erwre")));
Expected result:

Result: 0.
Actual result:

The script returns the result (0), but also a "PHP Strict Standards: Only
