HomeBackend DevelopmentPHP Tutorialphp mysql批量插入数据插入不完全

我用的是mysqli,一口气需要插入52条记录,偶尔会漏掉几条没插入成功,现在这个表3.4M,如果把这个表清空就不会出现这种情况?


回复讨论(解决方案)

才53条就会漏???什么破代码啊,贴出来看看

另:为啥不用 pdo?

不是代码的问题,这个数据库你可以把它想像成access.所以丢失数据的状况就不难理解了.
如果你希望用小数据库,那麽我建议你看一下mongoDB,这玩意前景不错,而且挺小的.

mysql 和 access 不是一个级别的数据库好么?
为什么丢失数据,可以不难理解?mysql丢失数据,在53条这种情况下很难理解!


顺便,mongoDB 不是小数据库,它是 nosql,和 mysql 又不是一回事了。比如 foursquare 就用它来处理 几百G的客户地理信息。

- -,好奇,这勋章怎么拿的。

mongoDB 真心不是小数据库…………大起来是很恐怖的一个东西
另外52条就漏太夸张了
建议用事务处理看看
如果还漏就是代码有问题

嗲!

这是我代码的错

我也有这种问题,但是不知道原因,估计是因为使用的mysql的扩展有问题,我用的是mysqli扩展

How do you loop through all the values stored in a PHP session?How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AM

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.

What are some common problems that can cause PHP sessions to fail?What are some common problems that can cause PHP sessions to fail?Apr 25, 2025 am 12:16 AM

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

How do you debug session-related issues in PHP?How do you debug session-related issues in PHP?Apr 25, 2025 am 12:12 AM

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

What happens if session_start() is called multiple times?What happens if session_start() is called multiple times?Apr 25, 2025 am 12:06 AM

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

How do you configure the session lifetime in PHP?How do you configure the session lifetime in PHP?Apr 25, 2025 am 12:05 AM

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.
