PHP-Handbuch: Opens a Sybase server connection

Beschreibung

resource sybase_connect ([ string $servername [, string $username [, string $password [, string $charset [, string $appname [, bool $new = false ]]]]]] )

sybase_connect establishes a connection to a Sybase server.

In case a second call is made to sybase_connect with the same arguments, no new link will be established, but instead, the link identifier of the already opened link will be returned.

The link to the server will be closed as soon as the execution of the script ends, unless it's closed earlier by explicitly calling sybase_close.

Parameter-Liste

servername: The servername argument has to be a valid servername that is defined in the 'interfaces' file.
username: Sybase user name
password: Password associated with username.
charset: Specifies the charset for the connection
appname: Specifies an appname for the Sybase connection. This allow you to make separate connections in the same script to the same database. This may come handy when you have started a transaction in your current connection, and you need to be able to do a separate query which cannot be performed inside this transaction.
new: Whether to open a new connection or use the existing one.

Rückgabewerte

Returns a positive Sybase link identifier on success, or FALSE on failure.

Changelog

Version	Beschreibung
5.3.0	The `new` parameter was added.
