Magento 2 0.42.0-beta1 is available since a few days. In order to test it right away, we will see how to install a running demo in 5 minutes sharp thanks to Docker. If you don't know Docker, please report to our previous tutorial.

We will even go further and give you the choice between two types of setup:

• a read-only discovery mode running instance of Magento 2 in order to discover the new admin interface and click
• a developer mode, in order to have a development environnement and start playing with the brand new technical features of Magento 2.

Disclaimer : We assume you have a running and fonctionnal Docker on your computer.

As the manual says, "If two members compare as equal, their order in the sorted array is undefined." This means that the sort used is not "stable" and may change the order of elements that compare equal. 

Sometimes you really do need a stable sort. For example, if you sort a list by one field, then sort it again by another field, but don't want to lose the ordering from the previous field. In that case it is better to use usort with a comparison function that takes both fields into account, but if you can't do that then use the function below. It is a merge sort, which is guaranteed O(n*log(n)) complexity, which means it stays reasonably fast even when you use larger lists (unlike bubblesort and insertion sort, which are O(n^2)). 

<?php 
function mergesort(&$array, $cmp_function = 'strcmp') { 
    // Arrays of size < 2 require no action. 
    if (count($array) < 2) return; 
    // Split the array in half 
    $halfway = count($array) / 2;
