説明

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

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().

パラメータ

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.

返り値

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

変更履歴

バージョン 説明
5.3.0 The new parameter was added.
