嚴格的標準誤差（）

Question

我想插入用戶的登記時間：

function InsertUserToSql() 
... 
$stmt = $this->dbh->prepare("INSERT INTO users 
(username, password, email, regdate) VALUES 
(:username,:password, :email, :regdate)"); 

     $stmt->bindParam(':username', $this->Username); 
     $stmt->bindParam(':password', $this->Password); 
     $stmt->bindParam(':email', $this->Email); 
     $stmt->bindParam(':regdate', time()); // this line shows the error 
     $stmt->execute(); 
... 

錯誤：Strict standards: Only variables should be passed by reference

Answer 1

$stmt = $this->dbh->prepare("INSERT INTO users 
(username, password, email, regdate) VALUES 
(:username,:password, :email, UNIX_TIMESTAMP())"); 

爲錯誤信息 - 這是相當googlable。
