don't quite get what she's asking for in the 3rd phase of this challenge.

Hi Jane, this particular task has caused a lot of confusion among the community, but hopefully this helps to get you started:

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

Although the task used the word parameter, the lot is really a property of the House object, much like the roof_color and wall_color. Since we know from the task that we need to return an array of these lots, we can create a $lots array and return it within the filterHouseColor method:

<?php

// add code below this comment

class Subdivision

{
   public $houses = array();

   public function filterHouseColor($color)
  {
    $lots = array();

    // Code to check whether the House object's roof_color OR wall_color match the $color parameter

    return $lots;
  }

}

?>

(If you're unfamiliar with the term 'lot' in this context, think of it as the designated area of land for each house to be built on)

Regarding the House objects themselves, there is already a $houses array available that you can loop through and run a conditional to check the wall_color / roof_color in comparison to the passed $color parameter. If there's a match, that house can be added to the $lots array as shown above.

Hopefully this helps to get you started without giving the answer away.

wow. that worked. thank you so much for your help.

When I add this code:

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

I get this error:

Bummer! Make sure you are checking both the "roof_color" AND "wall_color" to see if EITHER of them match the passed $color parameter.

What am I doing wrong??
