A little guidance here please.

Question

My proposed code is below and 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.

Here's what I get when I run the code below

Your return value should be an array.

Please help me to figure out what's going wrong.

index.php

<?php

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

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

?>

Alfredo,

This looks like a duplicate conversation. For the sake of keeping the answer in each conversation, I'll post what we had discussed here as well.

This is a confusing challenge. Here are a few details that the challenge doesn't give you that you need to know:

The houses property is an array of House objects.
The House class has three public member variables: lot, roof_color, and wall_color. You are supposed to loop through the houses array and create a separate array that only contains the House objects that have a roof_color or wall_color equal to the color passed to the filterHouseColor method. The result looks something like this:

public function filterHouseColor($color) { $matches = array(); for($i=0;$i<count($this->houses);$i++){ if ($this->houses[$i]->roof_color == $color || $this->houses[$i]->wall_color == $color) { $matches[] = array('lot' => $this->houses[$i]->lot); } } return $matches; }
