mysql - php队列计划任务怎么做呢，用的是ignore_user_abort吗？
我上次问了一个php队列使用场景和实现的问题，结果没人回答，然后我现在又看到了原来有这样一个函数ignore_user_abort 链接
难道php队列是这样实现的吗？这样脚本一直不断掉会有问题吗？
传统情况后台PHP脚本还在计算运行用户突然关闭浏览器会导致php执行到一半吗？比如发帖子，多条sql语句要执行，会受到客户端用户突然关闭浏览器断掉连接的影响吗？
希望大神帮我解答一下，谢谢了！

你的需求是什么？
队列计划任务和 ignore_user_abort 函数没关系。
如果你想要有一个常驻的 php 的进程去处理某项工作，你可以写个脚本 whiel(true) 在 console 下一直运行。
也可以创建 crontab 定时任务，每隔一段时间（比如，每秒执行，和常驻脚本效果差不了多少）。
这种情况专业的队列服务是很好的选择，比如rabbitmq ，beanstalkd。你也可以把异步任务存在数据库，然后用写一个驻留脚本去监控这个表，有新的任务就执行。
完全不懂题主想问什么，想要定时任务 如1楼所说，直接用crontab，cli方式执行PHP即可。至于ignore_user_abort 只是用来忽略浏览器中断的行为的

How to recover data after SQL deletes rows
Apr 09, 2025 pm 12:21 PM
Recovering deleted rows directly from the database is usually impossible unless there is a backup or transaction rollback mechanism. Key point: Transaction rollback: Execute ROLLBACK before the transaction is committed to recover data. Backup: Regular backup of the database can be used to quickly restore data. Database snapshot: You can create a read-only copy of the database and restore the data after the data is deleted accidentally. Use DELETE statement with caution: Check the conditions carefully to avoid accidentally deleting data. Use the WHERE clause: explicitly specify the data to be deleted. Use the test environment: Test before performing a DELETE operation.
