mysql_pconnect

Popis

Returns a positive MySQL persistent link identifier on success, or FALSE on error.

mysql_pconnect() establishes a connection to a MySQL server. The following defaults are assumed for missing optional parameters: server = 'localhost:3306', username = name of the user that owns the server process and password = empty password.

The server parameter can also include a port number. eg. "hostname:port" or a path to a socket eg. ":/path/to/socket" for the localhost.

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'.
