DB Connect issue

Hi All, I have an issue with a db connection the function for managing connect is function connect() { // connect to the database $status = $this->dbh = DB::connect($this->db_url); if (DB::isError($status)) { $this->connected = FALSE; $this->error = $status->getMessage(); echo 'Standard Message: ' . $this->error . "<br>"; } else { $this->connected = TRUE; } return $this->connected; } Now, I pass the connection string in the form 'mysql://user:pass@localhost/database' and get the error 'DB Error: not found'. I know its not the connection string that's at fault, because I can connect using the standard MySQL functions in PHP with those db credentials... Also, I know the function works fine, because I have the whole site up and running on another apache server and a Windows 2003 server... Anyone know what might be causing this? Thanks, Lee
