How to merge two arrays in PHP?

You can merge two arrays into one array using the array_merge function.

The sample code is as follows:

$array1 = [1, 2, 3];
$array2 = [4, 5, 6];

$result = array_merge($array1, $array2);

print_r($result);

The output results are:

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
    [5] => 6
)
