php socket

I initially opened a socket port. After a while, I closed the running php script (the socket port was not closed). When the script is re-run, how can I avoid repeatedly opening the socket port with the same IP + port? mistake? ? And how to reconnect to this port for normal communication? ?

If the process ends, the associated ports will also be unbound. If you reopen the port and cannot bind it, it means that your original process has not ended. Please check whether there are still original scripts in the process. In addition, wouldn't it completely solve this problem if you add the code to close the port when closing the script in the script?
