PHP and PDO class question

Question

I am very new to OOP styled PHP, and I am trying to implement PDO as well. I found this nice little class online which handles the database connection, however I have no ide

Answer 1

If you really must do database work from inside your Person object (separation of concerns says that this should be taken care of elsewhere), you can either pass it as a constructor argument (based on your usage, it looks like that may be the way you want to go), or as a setter injection. For the former:

class Person
{
    function __construct($db_handle)
    {
        // ... your existing code

Then you instantiate your person object like so:

$person = new Person($db_handle);

That's really the only way you can avoid needing to use $this->db_handler without copying the variable into local scope.
