The mysql_pconnect() function opens a persistent MySQL
connection.

This function returns the connection on success, or FALSE
and an error on failure. You can hide the error output by
adding an '@' in front of the function name.

mysql_pconnect() is much like mysql_connect(), but with two
major differences:

•This function will try to find a connection that's already
open, with the same host, username and password. If one is
found, this will be returned instead of opening a new
connection
•The connection will not be closed when the execution of
the script ends (mysql_close() will not close connection
opened by mysql_pconnect()). It will stay open for future
use
