resource ibase_pconnect(string $database[, string $username, string $password, string $charset, int $buffers, int $dialect, string $role, int $sync])
Opens a persistent connection to an InterBase database.
ibase_pconnect() acts very much like ibase_connect() with two major differences.
First, when connecting, the function will first try to find a (persistent) link that's already opened with the same parameters. If one is found, an identifier for it will be returned instead of opening a new connection.
Second, the connection to the InterBase server will not be closed when the execution of the script ends. Instead, the link will remain open for future use (ibase_close() will not close links established by ibase_pconnect()). This type of link is therefore called 'persistent'.
Returns an InterBase link identifier on success, or
FALSE on error.
- string $database: The
databaseargument has to be a valid path to database file on the server it resides on. If the server is not local, it must be prefixed with either 'hostname:' (TCP/IP), '//hostname/' (NetBEUI) or 'hostname@' (IPX/SPX), depending on the connection protocol used.
- string $username: The user name. Can be set with the ibase.default_user php.ini directive.
- string $password: The password for
username. Can be set with the ibase.default_password php.ini directive.
- string $charset:
charsetis the default character set for a database.
- int $buffers:
buffersis the number of database buffers to allocate for the server-side cache. If 0 or omitted, server chooses its own default.
- int $dialect:
dialectselects the default SQL dialect for any statement executed within a connection, and it defaults to the highest one supported by client libraries. Functional only with InterBase 6 and up.
- string $role: Functional only with InterBase 5 and up.
- int $sync:
