MySQL MySQL Database Connection

Question

Do I need to explicitly close the database connection after the query (and another database operation)?

Answer 1

Not unless you are sure you have completed a database connection to run the script. Even then, you do not need to explicitly close it, because PHP does this automatically after the script completes, if you are not using mysql_pconnect()to connect to your database.

Answer 2

No, php does this automatically. You might call it “good programming practice” to clear (also close mix).
