A braces are missing.

Why is there no prompt here!

First check the content of $ SQL _t

Toupiao_id name huodong_ID user_id time count
31 Zhang San 62 Peng Bin 23:23:27 21

It seems that there is no problem with the content. it's strange!

Another problem is that the IP address is the same for machines on the same vro. Only one ticket can be sent to machines on the same network. what should I do?

I also found that the IP addresses opened by the QQ browser are different from those obtained by different mobile phones on the same vro. the IP addresses obtained by other browsers on different mobile phones on the same route network are the same.

Wifi access, the ip address will not be the same!
For traffic access, the ip address should be the same
You need to have a unique identifier (via cookie or url) for user identification)
