int odbc_pconnect
(string dsn, string user, string password);
Returns an ODBC connection id or 0 ( false ) on error. 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.
Note: Persistent connections have no effect if PHP is used as a CGI program.
For more information on persistent connections, refer to the PHP3 FAQ.
