See www.php.net/array_pop.

Using: array_pop(array_keys($a)); array_keys($a) is an expression while array_pop 
expects a variable. ($k = array_keys($a);...).

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

Test script:
---------------
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 
variables should be passed by reference in" in my error log.
