Answer / p.sivasankar

1>>mysql_connect() — Open a connection to a MySQL Server

Description:
resource mysql_connect ([ string $server [, string
$username [, string $password [, bool $new_link [, int
$client_flags ]]]]] )
Opens or reuses a connection to a MySQL server

2>>mysql_pconnect — Open a persistent connection to a MySQL
server

Description:
resource mysql_pconnect ([ string $server [, string
$username [, string $password [, int $client_flags ]]]] )

Establishes a persistent connection to a MySQL server.

mysql_pconnect() acts very much like mysql_connect() with
two major differences.

First, when connecting, the function would first try to
find a (persistent) link that's already open with the same
host, username and password. If one is found, an identifier
for it will be returned instead of opening a new
connection.

Second, the connection to the SQL server will not be closed
when the execution of the script ends. Instead, the link
will remain open for future use (mysql_close() will not
close links established by mysql_pconnect()).

This type of link is therefore called 'persistent'
