Should be as simple as replacing the function call with an anonymous function.

usort($languages, function($a, $b) {
    if($a[0] == $b[0]) {
        return 0;
    }
    return $a[0] < $b[0] ? 1 : -1;
});

You can use the create_function as the callback function for earlier versions of php but now the create_function has been deprecated from the php7.2 and you need to use an anonymous function as @Alex Barker mentioned. Here is the link where you can see the deprecated function create_function
