sybase_close

(PHP 4, PHP 5, PHP 7)

sybase_close — Closes a Sybase connection

bool sybase_close ([ resource $link_identifier ] )

sybase_close() closes the link to a Sybase database that's associated with the specified link link_identifier.

Note that this isn't usually necessary, as non-persistent open links are automatically closed at the end of the script's execution.

sybase_close() will not close persistent links generated by sybase_pconnect().

link_identifier: If the link identifier isn't specified, the last opened link is assumed.

成功时返回 TRUE，或者在失败时返回 FALSE。
