Bug description: array_walk_recursive() modifies elements outside function
scope
Description:
------------
array_walk_recursive() modifies element values deeper than the first level
on vars outside the scope of the function call.
Reproduce code:
---------------
<?php
$ar = array(
'element 1',
array('element2 => subelement1')
);
func($ar);
var_dump($ar);
function func($a) {
array_walk_recursive($a, 'apply');
}
function apply(&$input, $key) {
$input = 'changed';
}
Expected result:
----------------
array(2) {
[0]=>
string(9) "element 1"
[1]=>
array(1) {
[0]=>
string(23) "element2 => subelement1"
}
}
Actual result:
--------------
array(2) {
[0]=>
string(9) "element 1"
[1]=>
array(1) {
[0]=>
string(7) "changed"
}
}
