ibase_pconnect

(PHP 4, PHP 5)

ibase_pconnect — Open a persistent connection to an InterBase database

Описание

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'.

Список параметров

database

The database argument 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.

username

The user name. Can be set with the ibase.default_user php.ini directive.

password

The password for username . Can be set with the ibase.default_password php.ini directive.

charset

charset is the default character set for a database.

buffers

buffers is the number of database buffers to allocate for the server-side cache. If 0 or omitted, server chooses its own default.

dialect

dialect selects 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.

role

Functional only with InterBase 5 and up.

sync

Возвращаемые значения

Returns an InterBase link identifier on success, or FALSE on error.
