array_replace
(PHP 5 >= 5.3.0, PHP 7)
array_replace — Replaces elements from passed arrays into the first array
Description
$array1
[, array $...
] ) : array
array_replace() replaces the values of
array1 with values having the same keys in each of 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 arrays overwriting the previous values.
array_replace() is not recursive : it will replace values in the first array by whatever type is in the second array.
Parameters
-
array1 -
The array in which elements are replaced.
-
... -
Arrays from which elements will be extracted. Values from later arrays overwrite the previous values.
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, $replacements2);
print_r($basket);
?>
The above example will output:
Array
(
[0] => grape
[1] => banana
[2] => apple
[3] => raspberry
[4] => cherry
)
