Object-Orientated PHP Code Final Code Challenge - Collection Objects

Hi there I am really stuck with this question it seems to jump from creating a property and a method on the class which I get no problem to then access a house object with a let property?

index.php 
<?php

// add code below this comment

class Subdivision

{

  public $houses = array();

  public function filterHouseColor($color)
  {

  }

}

?>

This is the question:

Return an array containing the public lot parameter of each house object whose public roof_color OR wall_color match the passed color parameter.

Gareth, something along these lines:

class Subdivision {
  public $houses = [];

  public function filterHouseColor($color) {
    $lots = [];  //create array

    foreach ($this->houses as $house) {  //loop through array

      if ($house->roof_color === $color || $house->wall_color === $color) {
        $lots[] = $house->lot; 
      }
    }

    return $lots;  
  }
}

Thank you jcorum, I was going down the road of trying to new up a house object and then add it to the houses array because I thought I would need a house object to work with. Is it me or is that question not very clear?

Your code worked great thank you.

$lots[] = $house->lot; needs to be changed to $lots[] = $house;
