Hi, I'm getting a persistent INVALID_LOGIN problem...

I am 100% sure the username and password are right.  I cut and paste them into the web login and that worked. 
The wsdl is a fresh download from this morning and it is accessible in that spot.



here's the code.  it's just a little POC for connecting to SF via PHP api and nothing is doing yet:

ini_set("soap.wsdl_cache_enabled", "0");
require_once (DIR_FS_SF_SOAP_CLIENT.'SforceEnterpriseClient.php');
require_once (DIR_FS_SF_SOAP_CLIENT.'SforceHeaderOptions.php');

try
{

   
    $mySforceConnection = new SforceEnterpriseClient ();
    $mySoapClient = $mySforceConnection->createConnection(DIR_FS_SF_SOAP_CLIENT."enterprise.wsdl.xml");
    $mylogin = $mySforceConnection->login("XXX", "YYY");

      $userResult = $mylogin->userInfo;
      print_r($userResult);
      echo $userResult->userFullName.', your session id is '.$mylogin->sessionId;

      $query = 'SELECT * FROM Opportunity';
      $response = $mySforceConnection->query(($query));

      print_r($response);

      foreach ($response->records as $record)
      {
       print_r($record);
      }

      print_r($mySforceConnection->getLastRequest());

      $bagent = $_SERVER["HTTP_USER_AGENT"];
      echo '<b>USER AGENT:</b> '.$bagent.'<br><br>';

}
catch (Exception $e)
{
  echo $e->faultstring;
}
