Including PHRETS into a Symfony2 project

Question

How can I include this library: https://github.com/troydavisson/PHRETS into a symfony project?

This is my composer.json:

    "name": "marysalcedo/reactive-pandora",
    "license": "proprietary",
    "type": "project",
    "autoload": {
        "psr-0": {

        },

    },

        ],
        "post-install-cmd": [

            "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::prepareDeploymentTarget"
        ],
        "post-update-cmd": [

        ]
    },
    "config": {
        "bin-dir": "bin"
    },
    "extra": {
        "symfony-app-dir": "app",

        "incenteev-parameters": {
            "file": "app/config/parameters.yml"
        }
    }
}

Whenever I try to use the object \PHRETS\Configuration I get an error:

new \PHRETS\Configuration();

This is the error I get back:

[Symfony\Component\Debug\Exception\ClassNotFoundException]                   
  Attempted to load class "Configuration" from namespace "PHRETS".             
  Did you forget a "use" statement for e.g.

Why isn't it being included?

try without the first slash as follow `new PHRETS\Configuration();` — jack, May 06 '15 at 18:21

Are you absolutely sure you actually installed the package?

1) I used custom composer-based project and tried to create new instance of that class and it worked. Output bellow.

2) Then I installed fresh copy of Symfony2 (v2.6) and the package. Tried creating instance and it worked as well.

Try this:

php composer.phar update

And then in your controller:

$c = new \PHRETS\Configuration();
var_dump($c);

Output in my setup:

object(PHRETS\Configuration)[570]
  protected 'username' => null
  protected 'password' => null
  protected 'login_url' => null
  protected 'user_agent' => string 'PHRETS/2.0' (length=10)
  protected 'user_agent_password' => null
  protected 'rets_version' => 
    object(PHRETS\Versions\RETSVersion)[571]
      protected 'number' => string '1.5' (length=3)
      protected 'valid_versions' => 
        array (size=5)
          0 => string '1.5' (length=3)
          1 => string '1.7' (length=3)
          2 => string '1.7.1' (length=5)
          3 => string '1.7.2' (length=5)
          4 => string '1.8' (length=3)
  protected 'http_authentication' => string 'digest' (length=6)
  protected 'strategy' => null
  protected 'options' => 
    array (size=0)
      empty

Side note

Just to clear the a confusion about use statements.

Putting use is not necessary when you specify class's FQN.
If you leave out the leading backslash PHP will try to find a an alias in you use statements that matches namespace. If none found, it will assume current class's namespace. Take well known Doctrine mapping example:
```
use `Doctrine\ORM\Mapping` as ORM
....
@ORM\Column() // This resolves to `Doctrine\ORM\Mapping\Column` `FQN`
```
If you would use class name only (e.g. Configuration) use statement would be mandatory.
