Operating system: windows + linux with php4.3.2
PHP version: 4.3.3
PHP Bug Type: Scripting Engine problem
Bug description: array passed by reference is modified but should'nt be
Description:
------------
When passing a non-existing portion of an array by reference this portion
gets created even if the function does not touch the array => it is
modified in the calling line.
It works with string indexes as well.
Reproduce code:
---------------
error_reporting(E_ALL);
$tab2 = array( );
function do_nothing ( &$var ) {
// code here doesnt matter
}
do_nothing($tab2[10]);
var_dump($tab2);
Expected result:
----------------
array(0) {
}
Actual result:
--------------
array(1) {
[10]=>
NULL
}
