Class Properties Annotation in PHP

I want to read comments defined in a specific format next to properties of a PHP Class. e.g.

Class Test
{
public $name; //(:Username)
public $Dob; //(:BirthDate)
}

I want a similar output like some array which gives me $name and Username I have tried with using PHP Reflection Class but it doesn't work like how I want it to be:

$reflection = new ReflectionClass('Test');
print_r($reflection->getProperty("name")->getDocComment());
