Bug description: explode or array_pop throws worning on
error_reporting(E_ALL|E_STRICT)
Description:
------------
Look at below code. on E_STRICT error_reporting either explode or
array_pop is throwing warning about passed by reference.
explode may returning something odd which causes array_pop to throw this
warning. else explode may have problem which throws this warning.
Below example shows both way with explode and without explode.
with explode it shows warning while without that it works fine.
Tested same thing on PHP version 5.2.10 and 5.2.6
Reproduce code:
---------------
<?php
error_reporting(E_ALL|E_STRICT);
$stack2 = array("orange", "banana", "apple", "raspberry");
$stack = "orange_banana_apple_raspberry";
var_dump(strtolower(array_pop(explode('_',$stack))));
var_dump(strtolower(array_pop($stack2)));
?>
Expected result:
----------------
string(9) "raspberry"
string(9) "raspberry"
Actual result:
--------------
Strict Standards: Only variables should be passed by reference in
/root/test.php on line 5
string(9) "raspberry"
string(9) "raspberry"
