using mysql_close()

Question

is it necessary to use mysql_close() at the end of a query in PHP?

Answer 1

In the manual :

mysql_close() closes the non-persistent connection to the MySQL server that's associated with the specified link identifier.

Using mysql_close() isn't usually necessary, as non-persistent open links are automatically closed at the end of the script's execution.
