sybase_connect
(PHP 4, PHP 5)
sybase_connect — Opens a Sybase server connection
说明
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().
