Connecting Composer libraries to Php site

Having understood the basic commands and the basics of how to work with Composer , we can begin to integrate it into our project.

Our project :

The project will have this simple structure for example

It will only contain the index.php file. The rest is already created by Composer itself.

What do we connect :

For example, let's include symfony/var-dumper from Symfony. Our /var/www/proj.loc/composer.json looks like this:

{
"name": "username/proj.loc",
"description": "Description",
"type": "proj.loc",
"license": "free",
"authors": [
{
"name": "username",
"email": "ad@min.loc"
}
],
"require": {
"symfony/var-dumper": "^2.0"
}
}

We do in the root of the project /var/www/proj.loc/ :

composer install

this creates a vendor folder. We need her. It will contain autoload.php .

We connect :

In the index.php file we place the autoload.php connection

<?php
include_once './vendor/autoload.php';

dump($_SERVER);>

If everything went well, then from the library pulled through Composer, the dump () function will become available;
