PDO bindParam未插入时间戳 - PDO bindParam Timestamp is not inserted

PDO bindParam Timestamp is not inserted

本文关键字：时间戳插入 bindParam PDO | 更新日期: 2023-09-27

我有以下PHP代码插入会话数据到一个名为ds_session的表:

    // session does not exists create insert statement
    $insertSQL = 'INSERT INTO ds_session (session_id, user_agent, session_expire, date_created, session_data)
                VALUES (:SESSION_ID, :USER_AGENT, :SESSION_EXPIRE, :DATE_CREATED, :SESSION_DATA)';
    $insertStmt = $this->pdo->prepare($insertSQL);
    $insertStmt->bindParam(':SESSION_ID', $id);
    $insertStmt->bindParam(':USER_AGENT', $_SERVER['HTTP_USER_AGENT']);
    $insertStmt->bindParam(':SESSION_EXPIRE', $time);
    $insertStmt->bindParam(':DATE_CREATED', time());
    $insertStmt->bindParam(':SESSION_DATA', $sessData);
    $insertResult = $insertStmt->execute();

我这里的问题是，参数SESSION_EXPIRE和DATE_CREATED没有设置。表定义如下所示:

CREATE TABLE `ds_session` (
  `session_id` varchar(32) NOT NULL default '',
  `user_agent` varchar(255) NOT NULL default '',
  `session_expire` datetime NOT NULL,
  `date_created` datetime NOT NULL,
  `session_data` longtext,
PRIMARY KEY  (`session_id`),
KEY `session_expire` (`session_expire`)
) ENGINE=MyISAM

这里有什么问题?我做错了什么与PDOStatement?

datetime值应该是字符串，而不是数字。使用FROM_UNIXTIME转换:

$insertSQL = 'INSERT INTO ds_session (session_id, user_agent, session_expire,
                    date_created, session_data)
            VALUES (:SESSION_ID, :USER_AGENT, FROM_UNIXTIME(:SESSION_EXPIRE),
                    FROM_UNIXTIME(:DATE_CREATED), :SESSION_DATA)';
