# array_replace

(PHP 5 >= 5.3.0, PHP 7, PHP 8)

array_replace — Replaces elements from passed arrays into the first array

### Description

array_replace(array `$array`, array `...$replacements`): array

array_replace() creates a new array and assigns items into it for each key in each of the provided arrays. If a key appears in multiple input arrays, the value from the right-most input array will be used.

array_replace() does not process elements items recursively, it replaces the entire value for each key when it does a replacement.

### Parameters

`array`

  The array in which elements are replaced.

`replacements`

  Arrays from which elements will be extracted. Values from later arrays overwrite the previous values.

### Return Values

Returns an array.

### Examples

Example #1 array_replace() example

`<?php
$base = array("orange", "banana", "apple", "raspberry");
$replacements = array(0 => "pineapple", 4 => "cherry");
$replacements2 = array(0 => "grape");
$basket = array_replace($base, $replacements, $replacements2);
var_dump($basket);
?>`

The above example will output:

    array(5) {
      [0]=>
      string(5) "grape"
      [1]=>
      string(6) "banana"
      [2]=>
      string(5) "apple"
      [3]=>
      string(9) "raspberry"
      [4]=>
      string(6) "cherry"
    }

Example #2 Example of how nested arrays are handled

`<?php
$base = [ 'citrus' => [ 'orange', 'lemon' ], 'pome' => [ 'apple' ] ];
$replacements = [ 'citrus' => [ 'grapefruit' ] ];
$replacements2 = [ 'citrus' => [ 'kumquat', 'citron' ], 'pome' => [ 'loquat' ] ];
$basket = array_replace($base, $replacements, $replacements2);
var_dump($basket);
?>`

The above example will output:

    array(2) {
      ["citrus"]=>
      array(2) {
        [0]=>
        string(7) "kumquat"
        [1]=>
        string(6) "citron"
      }
      ["pome"]=>
      array(1) {
        [0]=>
        string(6) "loquat"
      }
    }
