cubrid_pconnect — Open a persistent connection to a CUBRID server


Описание

resource cubrid_pconnect ( string $host , int $port , string $dbname [, string $userid [, string $passwd ]] )

Establishes a persistent connection to a CUBRID server.

cubrid_pconnect()() acts very much like cubrid_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, port, dbname and userid. 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 (cubrid_close() or cubrid_disconnect() will not close links established by cubrid_pconnect()).

This type of link is therefore called 'persistent'.
