sybase_pconnect

(PHP 3, PHP 4, PHP 5)

sybase_pconnect -- Open persistent Sybase connection

Description

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

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

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'.

See also sybase_connect().
