Make / link to the different directory VHost, PHP MVC

Question

Im trying to create my own MVC. My folder structure is following:

 localhost (root, htdocs)
   - Project_1
     - images
       - test.jpg
     - App
       - Controllers
       - Models
       - Views
     - Classes

Now if i create an index file under views folder and add this:

    <img src="/images/test.jpg" />

this does not load test.jpg because / points to localhost (root/htdocs) folder and does not point to Project_1

My question is what do i need to do to make / point to Project_1 directory instead of root, i know it has to do something with VHosts but unfortunately i do not know any tutorial that would explain the problem.

Any ideas/suggestions or links to tutorials will be appreciated. Thank you

NOTE: I do not want to do the following:

  define('ROOT', '/localhost/Project_1/');

and then use it like

  <img src="<?=ROOT?>images/test.jpg" />

this is what im trying to avoid

If all you are looking to do is change the base path of images then you might be able to get away with using the <base> HTML element.

Taken from MDN -
The HTML element specifies the base URL to use for all relative URLs contained within a document.

As for the PHP side of things, the option you categorically dismissed would probably be the best way - defining a constant pointing to the correct path -

define('ROOT', '/localhost/Project_1/');

If you want to get into the settings of your virtual host, then you'll be able to set your document root directly from the virtual host's definition. Here is a simple example -

<VirtualHost *:80>
    DocumentRoot /var/www/localhost/Project_1/
    ServerName Project_1.com
</VirtualHost>

Within this virtual host, your $_SERVER['DOCUMENT_ROOT'] will now be /var/www/localhost/Project_1/.
