From: php at koterov dot ru
Operating system: Windows XP
PHP version: 5.1.2
PHP Bug Type: Scripting Engine problem
Bug description: Suspicous reference-argument behavour at func($m=null)
Description:
------------
Seems assignment-and-passing by reference becomes broken in PHP 5.1.
PHP 4.x and 5.0 work as expected. See sample below.
Seems PHP assigns value to $x AFTER calling function f(), but NOT before
it. Or - only copy of $x passed to f(), not $x itself (as in 4.0 & 5.0).
Reproduce code:
---------------
<?php
function f(&$m)
{
$m = 123;
}
f($x=0);
var_dump($x);
?>
Expected result:
----------------
int(123)
Actual result:
--------------
int(0)
