Hi,

One of my new developments is going to be very OOP based, however earlier I came across an issue with this....

I have lots of different classes in lots of different files... e.g. one for MySQL connection and queries, and another for user registration and what not...

The problem I am having is how to give all of my classes access to the MySQL class via one instance so im not constantly making new objects in every class.

Im sorry if I haven't made this very clear - but basically all I am trying to do is to get the information from one class which acts as the base of the application into all of the other classes around it.

You could use extended classes.

PHP Code:

class YourRegistrationClass extends YourDBclass
{
    function register()
    {
        // call a function from YourDBclass
        $result = $this->query("...");
    }
} 

Or you could pass the instance to the other classes constructor.

PHP Code:

$db = new YourDBclass();

$registration = new YourRegistrationClass($db);

class YourRegistrationClass
{
    public $db;

    public function __construct(YourDBclass $db)
    {
        $this->db = $db;
    }
}

I was considering using extended classes, but I wasnt sure if that was the right approach.

Thanks for your help, I'll have another shot at it.
