PHP Bug Type: Scripting Engine problem
Bug description: Array doesn't pop when array is created inside array_pop
Description:
------------
If you create an array inside array_pop(), expecting that array to be
popped then it isn't even though the last element of that array is
returned as expected.
Creating the array on the previous line makes array_pop() behave as
expected.
This behaviour doesn't occur in PHP4.3.x on FreeBSD. I only noticed it
when I upgraded to PHP 5.1.2 on my home WinXP machine though it's possible
it was broken but I didn't notice it in 5.0.x
Reproduce code:
---------------
$a=array(0, 1, 2, 3, 4, 5); // Set array first.
$offcut=array_pop($a); // Then pop array.
$length=count($a);
echo "<pre>Array offcut: "
.$offcut."\nArray length: "
.$length."\nLast element: "
.$a[$length-1]."</pre>\n";
$offcut=array_pop($a=array(0, 1, 2, 3, 4, 5)); // Set and pop at the same
time.
$length=count($a);
echo "<pre>Array offcut: "
.$offcut."\nArray length: "
.$length."\nLast element: "
.$a[$length-1]."</pre>\n";
Expected result:
----------------
Array offcut: 5
Array length: 5
Last element: 4
Array offcut: 5
Array length: 5
Last element: 4
Actual result:
--------------
Array offcut: 5
Array length: 5
Last element: 4
Array offcut: 5
Array length: 6
Last element: 5
