Joins as array

[eluser]skribe[/eluser]
Sorry my brain has vacated the premises and so I'm having difficulties attempting to loop through an array to produce a join. ie

Code:

$joins = array(
                   array('contact', 'contact.id = person.id', 'left'),
                   array('info', 'info.id = person.id','left)
                             );

                foreach($joins as $join){
                   foreach($join as $item) {                    
                        something
                   }
                    $this->db->join(something);
                }

Any suggestions?
