MAC osx strange behaviour

How to set class variables dynamically?

Consider the following code:
class Project
{
    public $ProjectID;
}   
class Work
{
    public $WorkID;
}   

public function setToSeven($pData, $name)
{
    $pData->{$name . 'ID'} = 7
}

$p = new Project();
$w = new Work();
setToSeven($w, 'Work');
setToSeven($p, 'Project');

echo $p . ' -- ' . $w;
Now how would I go about setting the variable in a dynamic way?MAC osx strange behaviour
