Quick OOP Question

[Demonic]

Alright say you have 2 classes, one is a sql class and another is a authentication class.  The db class uses class methods to store data, if I extend the sql class in the authentication class, will I be able to use the parent classes methods?

 

In the sql class there is:

public function query($query) {
	$this->query = mysql_query( $query ) or trigger_error("There was a mysql error:" . mysql_error(), E_USER_ERROR);
}

 

query stores the sql resource so when i extend the sql class will the current child class have a newly create query method for use?

 

Want to make sure that's correct or not.

Yes, classes which extend another actually have all the public methods of the parent available to them. This is all covered in the manual.

 

Having said that, why on earth would an authentication class extend a database class? They are in no way related.
