Description:
------------
To be specific, this only occurs when passing a reference returned by a
function
into another function that takes a reference.
This behaves as expected with a variable instead of a function call, so I
believe
this is a bug.
Test script:
---------------
<?php
function &return_a() {
global $a;
return $a;
}
$a = [1,2,3];
array_shift(return_a());
print_r($a);
$a = [1,2,3];
array_shift((return_a()));
print_r($a);
Expected result:
----------------
Array
(
[0] => 2
[1] => 3
)
Array
(
[0] => 2
[1] => 3
)
Actual result:
--------------
Array
(
[0] => 2
[1] => 3
)
Array
(
[0] => 1
[1] => 2
[2] => 3
)
