Hi Zubain 1.) the actuall difference between mysql_connect and mysql_pconnect is very simple. *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.that means u can actually reuse the 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'. 2.) about ur second query i cannot understand. :).
