Bug description: array_merge_recursive mangles input arrays
Similar to #14990 (exept that the demo code there runs fine) and the first
source array gets mangled.
Example
=========
<pre><?
$a = array(
'a1' => 1,
'a2' => array( 1, 2, 3 ),
'a3' => array(
'a' => array( 10, 20, 30 ),
'b' => 'b'
)
);
$b = array( 'a1' => 2,
'a2' => array( 3, 4, 5 ),
'a3' => array(
'c' => 'cc',
'a' => array( 10, 40 )
)
);
$c['result'] = array_merge_recursive( $a, $b );
$c['a'] = $a;
$c['b'] = $b;
print_r( $c );
?>
Example Output
================
Array
(
[result] => Array
(
[a1] => Array
(
[0] => 1
[1] => 2
)
[a2] => Array
(
[0] => 1
[1] => 2
[2] => 3
[3] => 3
[4] => 4
[5] => 5
)
[a3] => Array
(
[a] => Array
(
[0] => 10
[1] => 20
[2] => 30
[3] => 10
[4] => 40
)
[b] => b
[c] => cc
)
)
[a] => Array
(
[a1] => 1
[a2] => Array
(
[0] => 1
[1] => 2
[2] => 3
[3] => 3
[4] => 4
[5] => 5
)
[a3] => Array
(
[a] => Array
(
[0] => 10
[1] => 20
[2] => 30
[3] => 10
[4] => 40
)
[b] => b
[c] => cc
)
)
[b] => Array
(
[a1] => 2
[a2] => Array
(
[0] => 3
[1] => 4
[2] => 5
)
[a3] => Array
(
[c] => cc
[a] => Array
(
[0] => 10
[1] => 40
)
)
)
)
