note 25688 deleted from function.get-class-vars by nlopess

Note Submitter: alex at linium dot net ---- Although this is pointed out in the docs, it should be stressed that this functions does not return an array of the the variable names a class contains, but an associative array in which the variable names are the keys. To get an array of the variable names, use: $array = array_keys(get_class_vars($classname));
