Object-Oriented PHP Basics: I'm stuck at this function, don't know what is wrong, don't know how to proceed

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

Any help would be appreciated.

Many thanks.

index.php 
<?php

// add code below this comment

Class Subdivision
{
    public $houses = array(); 

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

      return $lots;
    }
}

?>

try using foreach($this->houses as $house) PHP seems to need to be told that the variable is on the current object.
