Here's an example of related activities (4.1.1):
<?php
$a = array(4 => '4 a', 2 => '2 a', 'foo' => 'foo a');
$b = array(4 => '4 b', 1 => '1 b', 'foo' => 'foo b');
$c['plus'] = $a + $b;
$c['merge'] = array_merge($a,$b);
$c['merge_recursive'] = array_merge_recursive($a,$b);
$c['concat'] = $a . $b;
print_r($c);
?>
The behavior of . both seems weird yet mostly makes sense too. I agree,
the use of '+' needs to be documented. Documented with
similarities/differences between array_merge and array_merge_recusive.
Some obvious differences can be seen through the above example, who will
document this and where? :)
I just reported bug #14990 on array_merge_recursive which may be of
interest. Without further ado, here's the output from the above code:
Array
(
[plus] => Array
(
[4] => 4 a
[2] => 2 a
[foo] => foo a
[1] => 1 b
)
[merge] => Array
(
[0] => 4 a
[1] => 2 a
[foo] => foo b
[2] => 4 b
[3] => 1 b
)
[merge_recursive] => Array
(
[0] => 4 a
[1] => 2 a
[foo] => Array
(
[0] => foo a
[1] => foo b
)
[2] => 4 b
[3] => 1 b
)
[concat] => ArrayArray
)
