With 3+ parameters, only the first parameter is left untouched. All
others are affected, as demonstrated above with $b.

In Summary:
--------------
array_merge_recursive() modifies the array entered as the second
parameter if the merged arrays have at least one identical stringed
key. It will affect all such duplicate keys, and modify the second
parameter's array as demonstrated below.
Example:
--------------
<?php
$a = array(2 => '2 a', 'foo' => 'foo a','bar' => 'bar a');
$b = array(2 => '2 b', 'foo' => 'foo b','bar' => 'bar b');
$c['recursive'] = array_merge_recursive($a,$b);
$c['a'] = $a;
$c['b'] = $b;
print_r($c);
?>
Example output:
---------------
Array
(
[recursive] => Array
(
[0] => 2 a
[foo] => Array
(
[0] => foo a
[1] => foo b
)
[bar] => Array
(
[0] => bar a
[1] => bar b
)
[1] => 2 b
)
[a] => Array
(
[2] => 2 a
[foo] => foo a
[bar] => bar a
)
[b] => Array
(
[2] => 2 b
[foo] => Array
(
[0] => foo b
)
[bar] => Array
(
[0] => bar b
)
)
)
Notes:
----------------
Notice how in $b, keys 'foo' and 'bar' are now arrays when initially
they were not. This behavior exists with all such duplicate stringed
keys. array_merge_recursive() should not directly affect inputted
values. This seems related to bug
#14128.
