Check For House Color Of Roof or Walls

I'm trying to figure out why my code isn't allowing me to move on to the next stage.

index.php
<?php

// add code below this comment

class Subdivision
{
  public $houses = array();

  public function filterHouseColor($color)
  {
    $lots = array();
    if (($houses->roof_color == $color) || ($houses->wall_color == $color)) {
      $lots[] = $houses;
    }
    return $lots;
  }
}

?>

I found that it gives you an incorrect message. For me it was telling me that i wasn't testing on both roof and house color, but what was missing was $this. i always forget the $this, since in the languages i use, you don't have to use it.

<?php
class Subdivision
{
// add code below this comment
  public $houses = array();

  public function filterHouseColor($color)
  {
    $lots = array();
    foreach($this->houses as $house)
    {
        if ($house->roof_color == $color){
          $lots[] = $houses->lot;
        }
        else if ($house->wall_color == $color){
          $lots[] = $houses->lot;
        }
    }
    return $lots;
  }
}
?>

Thank you! I also forgot $this and was getting frustrated trying to figure out what was wrong.
