array_replace_recursive

Replaces elements from passed arrays into the first array recursively

array **array_replace_recursive** array $array array $replacements

replaces the values of
with the same values from all the following

arrays. If a key from the first array exists in the second array, its value will be replaced by the value from the second array. If the key exists in the second array, and not the first, it will be created in the first array. If a key only exists in the first array, it will be left as is. If several arrays are passed for replacement, they will be processed in order, the later array overwriting the previous values. array_replace_recursive``array

is recursive : it will recurse into

arrays and apply the same process to the inner value. array_replace_recursive

When the value in the first array is scalar, it will be replaced by the value in the second array, may it be scalar or array. When the value in the first array and the second array are both arrays, will replace their respective value recursively. array_replace_recursive

arrayThe array in which elements are replaced.

replacementsArrays from which elements will be extracted.

Returns an . array

Voorbeeld: example

<?php
$base = array('citrus' => array("orange"), 'berries' => array("blackberry", "raspberry"));
$replacements = array('citrus' => array('pineapple'), 'berries' => array('blueberry'));

$basket = array_replace_recursive($base, $replacements);
print_r($basket);

$basket = array_replace($base, $replacements);
print_r($basket);
?>

Array
(
    [citrus] => Array
        (
            [0] => pineapple
        )

    [berries] => Array
        (
            [0] => blueberry
            [1] => raspberry
        )

)
Array
(
    [citrus] => Array
        (
            [0] => pineapple
        )

    [berries] => Array
        (

        )

)

Voorbeeld: and recursive behavior

<?php
$base = array('citrus' => array("orange") , 'berries' => array("blackberry", "raspberry"), 'others' => 'banana' );
$replacements = array('citrus' => 'pineapple', 'berries' => array('blueberry'), 'others' => array('litchis'));
$replacements2 = array('citrus' => array('pineapple'), 'berries' => array('blueberry'), 'others' => 'litchis');

$basket = array_replace_recursive($base, $replacements, $replacements2);
print_r($basket);

?>

Array
(
    [citrus] => Array
        (
            [0] => pineapple
        )

    [berries] => Array
        (
            [0] => blueberry
            [1] => raspberry
        )

    [others] => litchis
)
