The prototype of the mysqli_stmt constructor is mysqli_stmt::__construct(mysqli $link, $query);
To extend mysqli_stmt, do
class myStmt extends mysqli_stmt {
public function __construct($link, $query) {
parent::__construct($link, $query);
}
}
class myI extends mysqli {
public function prepare($query) {
return new myStmt($this, $query);
}
}
