There are two different connections available, if you are connecting to a MySQL database in your PHP application, mysql_connect – which set up a new connection “each time” and mysql_pconnect which uses persistent connections.<\/p>\n
Mysql_connect opens a new connection each time a PHP page is called, and closes the connection down again at the end of the request. It is perfect for pages that do not have a heavy usage.<\/p>\n
Mysql_pconnect will also open a new connection when a PHP page is called, but it will NOT close the connection at the end of the request – instead, it will put aside it in a connection pool so that a succeeding request can persist to use the same connection. It’s intended for pages that have a heavy usage – where the resources burn up by opening and closing connections every time might reduce performance.<\/p>\n
But mysql_pconnect need some tuning of the servers and you may require limiting the numbers of connections \/ children and configuring timeouts and how to deal with idle children.<\/p>\n
By using this you have some drawbacks as follows.
\nIt does NOT give you sessions.
\nIt does NOT give you a per-site-visitor login.
\nIt does NOT give you any added functionality.<\/p>\n","protected":false},"excerpt":{"rendered":"
