# array_replace_recursive

(PHP 5 >= 5.3.0)

array_replace_recursive — Replaces elements from passed arrays into the first array recursively

### Descrição

array array_replace_recursive ( array `&$array` , array `&$array1` [, array `&$array2` [, array `&$...` ]] )

array_replace_recursive() replaces the values of the first `array` 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() is recursive : it will recurse into arrays and apply the same process to the inner value.

When the value in `array` is scalar, it will be replaced by the value in `array1`, may it be scalar or array. When the value in `array` and `array1` are both arrays, array_replace_recursive() will replace their respective value recursively.

### Parâmetros

`array`

  The array in which elements are replaced.

`array1`

  The array from which elements will be extracted.

### Valor Retornado

Returns an array , or `NULL` if an error occurs.

### Exemplos

Exemplo #1 array_replace_recursive() 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);
?>`

O exemplo acima irá imprimir:

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

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

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

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

    )

Exemplo #2 array_replace_recursive() 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);
?>`

O exemplo acima irá imprimir:

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

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

        [others] => litchis
    )
