www.text + php + c# issue

I’m testing the WWW class functionality but I’m having problems to retrieve the data from the server. Since posting data is ok, I'll skip that bit.

On the server side, unityOut.php

 <?php
    
     $sql = "SELECT * FROM unity ORDER BY cod_user DESC";        
     $consulta = mysql_query($sql, $conexion);
 
     while($reg = mysql_fetch_array($consulta)){         

         echo $reg["name"];    
         echo $reg["extra_field"];    
     }

?>

That code connects with DB ok, since I can look for the website and see it on the browser:

Now, on the Unity C# side, I want to retrieve that data:

     public string url = "http://...url.../unityOut.php";      
     private WWW www;        

     void OnGUI ( ) {
         
         if (GUI.Button(new Rect(8*unitW, 5*unitH, 8*unitW, 2*unitH), "Get data")){            
             StartCoroutine("getData");
         }                        
     }     

      IEnumerator getData(){
         
         www = new WWW(url);
         yield return www;
         Debug.Log("hello: " + www.text);
         }
     }
 }

I'm ok with parsing whatever it comes, but, at this moment... All I get for www.text is the html label. Any clues of what am I missing?

Thanks
