array_merge_recursive
(PHP 4 >= 4.0.1)
array_merge_recursive -- Merge two or more arrays recursively
Description
array array_merge_recursive ( array array1, array array2
[, array ...])
array_merge_recursive() merges the elements of two or more
arrays together so that the values of one are appended to
the end of the previous one. It returns the resulting array.
If the input arrays have the same string keys, then the
values for these keys are merged together into an array,
and this is done recursively, so that if one of the values
is an array itself, the function will merge it with a corresponding
entry in another array too. If, however, the arrays have
the same numeric key, the later value will not overwrite
the original value, but will be appended.
Example 1. array_merge_recursive() example
<?php
$ar1 = array("color" => array("favorite"
=> "red"), 5);
$ar2 = array(10, "color" => array("favorite"
=> "green", "blue"));
$result = array_merge_recursive($ar1, $ar2);
?>
The $result will be:
Array
(
[color] => Array
(
[favorite] => Array
(
[0] => red
[1] => green
)
[0] => blue
)
[0] => 5
[1] => 10
)
