[](#installation)

    "require": {
        "hgg/parameter-validator": "dev-master"
    }
}
```

Use Cases
---------

[](#use-cases)

### Url Query String Parameters

[](#url-query-string-parameters)

A framework like Symfony 2 provides the Request object from which one can obtain the query string parameters either one by one

```
$param = $request->query->get('name-of-parameter');
```

or all at once

```
$params = $request->query->all();
```

This is really convenient but the validation of these parameters is still left to the developer and becomes really tedious. You still have to ensure that all required parameters are present and that the values for them are of the correct type, etc.

This framework allows the definition of rules for the parameters and can even validate the values for these parameters.
