To merge arrays in PHP all you have to do is use the array_merge() function like shown below:
<?php
$array1 = array("Matt", "Michael", "Justin");
$array2 = array("Janice", "Janet", "Kylie");
$array3 = array_merge($array1, $array2);
?>
One thing to remember when merging arrays is you might be creating duplicate results, if you don't want 2 or more of the same result in the array remember to use the function array_unique() to remove the duplicate results from it!

What is the use of auxiliary array in merge sort?
In merge sort the whole is divided into two sub arrays. (This way of solving problem is called Divide and conquer algorithm) These sub arrays are called auxiliary arrays. First an array A is divided into two auxiliary arrays A1 and A2. Now these auxiliary arrays are further divided until we reach a stage with an auxiliary array of 2 elements. These 2 elements are arranged in incremental order and merged with the previous divided arrays. So we can say that auxiliary array is used to implement the basic principle of merge sort.

How are arrays different in languages other than PHP?
There aren't any (at least none that I'm aware of). In PHP arrays are the same as in all other languages: variables that contain several values at different indices.The only difference between PHP and certain other languages is the way a variable is initialised as an array:$example = array(index => value, index2 => value2);Contrary to other languages, this is similar to a function, as opposed to creating an instance of a class. (JavaScript for example: xyz = new Array();)
