Operating system:
PHP version: 4.3.10
PHP Bug Type: Scripting Engine problem
Bug description: array passed by reference is modified but should'nt be
Description:
------------
Bug #26030 realtes to the same problem and should be reopened: Why? It
seems to be *NOT* related to #25996, as formerly reported by
[EMAIL PROTECTED], which was the reason to close it.
Problem:
If a part of an array, that does not yet exist, is passed to a function by
reference, this part will be created automatically and filled with NULL.
As long as no there is no function implemented to delete the NULL entry
(unset does not work), this behavior cannot be correct.
Please see my example - it clearly states that the behavior is incorrect.
Reproduce code:
---------------
See why:
The following behavior *cannot* be intentional:
<?php
function func(&$a)
{
// void();
}
$a['one'] =1;
func($a['two']);
?>
var_dump($a) returns
array(2) {
["one"]=>
int(1)
["two"]=>
NULL
}
Expected result:
----------------
array(2) {
["one"]=>
int(1)
}
Actual result:
--------------
array(2) {
["one"]=>
int(1)
["two"]=>
NULL
}
