Open persistent Sybase connection

说明

resource sybase_pconnect ([ string $servername [, string $username [, string $password [, string $charset [, string $appname ]]]]] )

sybase_pconnect() acts very much like sybase_connect() with two major differences.

First, when connecting, the function would first try to find a (persistent) link that's already open with the same host, username and password. If one is found, an identifier for it will be returned instead of opening a new connection.

Second, the connection to the SQL server will not be closed when the execution of the script ends. Instead, the link will remain open for future use (sybase_close() will not close links established by sybase_pconnect()).

This type of links is therefore called 'persistent'.

参数

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

返回值

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