RE: [PHP] Missing arguments for function in class? (object-orientedprogramming)

rename either the function or the class. class Display_Records { function display_records($row, $record_count) { $current_date = (date("Y-m-d")); $age = ($current_date); return $age; } function disp_rec($row, $record_count) { $current_date = (date("Y-m-d")); $age = ($current_date); return $age; } } $d = new Display_Records(); // no problem here print $d -> disp_rec('row', 'record cont'); // big problem here print $d -> display_records('row', 'record cont'); > -----Original Message----- > From: Thomas David Kehoe [mailto:kehoe@casafuturatech.com] > Sent: Wednesday, June 27, 2001 9:27 AM > To: php-general@lists.php.net > Subject: [PHP] Missing arguments for function in class? > (object-orientedprogramming) > > > I have a function that works perfectly (from within a script).
