To merge and sort an array in PHP you need to use the array_merge() and sort() functions like shown in the example below:
<?php
$array1 = array(1, 5, 3, 9, 7);
$array2 = array(8, 2, 6, 4, 0);
// merge the arrays
$merge = array_merge($array1, $array2); // 1, 5, 3, 9, 7, 8, 2, 6, 4, 0
// sort the array
sort($merge); // 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
