Advantages of getPost over $_POST

Question

Are there any advantages of Yii::app()->request->getPost() over $_POST?

I feel it makes the code too much object oriented.

Answer 1

CHttpRequest::getPost() checks if the parameter exists first and if not it returns a default value that you can pass to it.

Here is its actual implementation:

public function getPost($name,$defaultValue=null)
{
    return isset($_POST[$name]) ? $_POST[$name] : $defaultValue;
}
