php mysqli连接的最长时间是多少

Question

I have a long running php script that sends out emails and updates the database. The script takes about 45 minutes to complete. I have a progress indicator in which I can see on which iteration of the loop problems could occur. Always after about 12 minutes an error unknown error occurs. There's no problem with the mailing script. It looks to me like the mysql database connection is dropped. Is there a way to extend the duration of the connection? Thanks

I think it's not a problem with mysqli , but you can look for max_execution_time in your php.ini file and change it to a suitable value. Here you can read more about this.

But it's better to check your server log to get more insight of your problem.
