(PHP 4 >= 4.0.2, PHP 5 < 5.1.0, PECL ingres >= 1.0.0)

ingres_close — Close an Ingres database connection

说明

ingres_close ( resource $link ) : bool

ingres_close() closes the connection to the Ingres server that is associated with the specified link.

ingres_close() is usually unnecessary, as it will not close persistent connections and all non-persistent connections are automatically closed at the end of the script.

参数

link: The connection link identifier

返回值

成功时返回 TRUE，或者在失败时返回 FALSE。
