php - MYSQL Query not able to pull data from Database -

The problem I have is that my query:

  SELECT * to the Administrator Administrator WHERE nombre_administrador =? And password =?   
 Nothing is pulling from the database.  
  var_dump  Shows:  
  public 'Infect_rows' = & gt; Blank, public 'insert_id' = & gt; Nulled public 'num_rows' = & gt; Blank Public 'param_count' = & gt; Null public 'field_count' = & gt; Weak public 'error' = & gt; Weak public 'error' = & gt; Null public 'error_list' = & gt; Zero public 'sqlstate' = & gt; Weak public 'id' = & gt; Null
