odbc_pconnect
(PHP 4, PHP 5)
odbc_pconnect — Open a persistent database connection
说明
resource odbc_pconnect ( string $dsn , string $user , string $password [, int $cursor_type ] )Opens a persistent database connection.
This function is much like odbc_connect(), except that the connection is not really closed when the script has finished. Future requests for a connection with the same dsn, user, password combination (via odbc_connect() and odbc_pconnect()) can reuse the persistent connection.
参数
See odbc_connect() for details.
返回值
Returns an ODBC connection id or 0 (FALSE) on error.
注释
Note: Persistent connections have no effect if PHP is used as a CGI program.
