array **array_replace** array $array array $replacements

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. array_replace

arrayThe array in which elements are replaced.

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

Returns an . array

Voorbeeld: 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);
?>

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

Voorbeeld: 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);
?>

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