using namespace shortly

Earlier, we learned how to use namespaces.
Let's learn how to use namespaces shortly. Use the use keyword.

How to use keyword

use namespace\class as short name;  

For example, if you shorten \hello\hello, the namespace you used earlier to hh,

use \hello\hello as hh;

Let's see if it works by example.

<?php
    namespace hello;

    class hello
    {
        function hello()
        {
            return 'first hello class.';
        }
    }

    namespace hello2;

    class hello
    {
        function hello()
        {
            return 'second hello class.';
        }
    }

    use \hello\hello as hh;
    use \hello2\hello as hh2;

    $helloFirst = new hh;
    echo $helloFirst->hello();
    echo '<br>';
    $helloSecond = new hh2;
    echo $helloSecond->hello();
?>

Result

If you use this once, you can save a little bit later.
