Will the server itself close the connection?

Question

PHP

Hello. Actually I use mysql. But I do not use the procedure for closing the connection. Question: If you do not close the server itself, will the server itself close the connection?

Answer 1

if you do not have a daemon, then when the script ends, the connection will close itself, if this is not a permanent connection, of course.

Answer 2

Closing a connection is good manners, just like closing files.
