无法使mssql_connect正常工作

I'm trying to connect to a specific local server using mssql_connect method but not having any luck.

Any Ideas?

mssql_connect('10.12.179.66:1433\ONE_ROOF_PROD', 'username', 'password');

Let php tell you more about the cause of the error.

error_reporting(E_ALL); ini_set('display_errors', 1);

$link = mssql_connect('10.12.179.66:1433\ONE_ROOF_PROD', $uid, $pass);
if ( !$link ) {
  if ( function_exists('error_get_last') ) {
    var_dump(error_get_last());
  }
  die('connection failed');
}

In case you are using windows you might also be interested in the sqlsrv extension.
