演示代碼報錯？
private?function?_isUsernameExists($username){
????$sql?=?'SELECT?*?FROM?`user`?WHERE?`username`=:username';
????$stmt?=?$this->_db->prepare($sql);
????$stmt?->bindParam(':username',$username);
????$stmt?->execute();
????$result?=?$stmt->fetch(PDO::FETCH_ASSOC);
????return?!empty($result);
?}$stmt = $this->_db->prepare($sql);這行代碼一直報錯？

報什么錯。一般報錯應該是你pdo_myqsl擴展沒開
