How to merge two arrays together in php

When you need to join or merge two arrays together you can use the php array_merge() function to do it. This function will return the merged array.
Look at the following code and see how the index reassigned.

<?php

$first_array = array(1, 2, 3, 4, 5, 6);
$second_array = array(10, 9, 7, 3, 5);

$new_array = array_merge($first_array, $second_array);

echo '<pre>';
print_r($new_array);
echo '</pre>';

/*

OUTPUT

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
    [5] => 6
    [6] => 10
    [7] => 9
    [8] => 7
    [9] => 3
    [10] => 5
)
