array_replace

Replaces elements from passed arrays into the first array

&reftitle.description; `array` `array_replace` `array` `array` `array` `replacements`

`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.

&reftitle.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.

&reftitle.returnvalues;

Returns an `array`.

### `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);
    ?>

&example.outputs;

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

### 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);
    ?>

&example.outputs;

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