I don't understand this Code Challenge

The instructions in this code challenge are too vague. I successfully completed steps one and two. I then, to the best of my understanding of the instructions in Step 3, wrote the code. I'm getting an error but if I had better instructions I could complete the challenge. I'm experienced with OOP PHP but it seems like the author of this challenge is making assumptions that aren't conveyed to the end user.

index.php 
<?php

// add code below this comment
class Subdivision
{
  public $houses;

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

Hey Alex,

I completely agree and feel your pain. With that said and how 'stuck' I am with this other challenge I am just going to give you the code I figured out for yours (I actually save all my answers), but I don't really remember why or how I came to this answer. I hope it makes sense for you and helps you out. :)

<?php

class Subdivision
{
  public $houses = array();

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

?>

Keep Coding! :dizzy:

Hi Jason,

I had noticed you forgot the greater than symbol for the object operator inside your if block.

$arr[] = $ahouse-lot; // should be $arr[] = $ahouse->lot;

The code still passed though so I think there is a problem with this challenge.

Thanks for the reply! Ha! I knew I had it right, was going nuts trying different options.
