Array Dereference in PHP 5.4 PRO

As of PHP 5.4 we can develop a function that returns an array and treat the call to that function as an array we want to access its elements.

<?php
function doSomething()
{
    $vec = [23,53,75,64];
    return $vec;
}

echo doSomething()[0];
?>

The following video clip shows the execution of this code sample and explains it.
