Extending a PEAR class

Hi All,

For a project I'm working on I wanted to be able to add extra
functionality to Pear's DB class. I can add the functionality as
stand-alone functions, but as they were to do with the database
connection I thought it would make sense to wrap them up into a class
that extended the Pear::DB class.

So, I whipped this up to test:

class BobDB extends DB {
function myfunction($param) {
return true;

$bobdb = bobdb::connect('mysql://root@localhost/mydb');
return $bobdb->myfunction('hello');

PHP liked that in terms of syntax but the reference to myfunction
returned "Fatal error: Call to undefined function: myfunction()"

Now I know this problem is something to do with calling the PEAR::DB
class statically (using the :: operator) but I'm not sure how to get
around it.

I tried going down the $bobdb = new bobdb(); path but got lost with how
PEAR creates it's own instances of it's classes.

Any help appreciated.
