I get an error saying I need to consider both "roof_color" and "wall_color" and check them against the parameter $color.
--- Php public function filterHouseColor($color) { $output = array(); foreach($this->houses as $dwelling) { if ($dwelling->roof_color == $color || $dwelling->wall_color == $color) { $output[] = $dwelling; } return $output; }
}
The previous two tasks are acceptable, but I cannot figure out what is wrong with my conditional statement. Cheers
<?php
// add code below this comment
class Subdivision
{
public $houses = array();
public function filterHouseColor($color)
{
$output = array();
foreach($this->houses as $dwelling) {
if ($dwelling->roof_color == $color || $dwelling->wall_color == $color) {
$output[] = $dwelling;
}
return $output;
}
}
}
?>

Treehouse TeacherHi there, Mike Womack ! You're doing terrific! You've understood the problem exceedingly well. This all comes down to placement. Namely, the placement of your return statement. You are returning the value a bit early. That return happens inside the foreach loop. Once a return is hit, the loop stops execution.
Right now, your code looks like this:
foreach($this->houses as $dwelling) { // begin foreach
if ($dwelling->roof_color == $color || $dwelling->wall_color == $color) { // begin if
$output[] = $dwelling;
} // end if
return $output;
} // end foreach
But you meant to do this:
foreach($this->houses as $dwelling) { // begin foreach
if ($dwelling->roof_color == $color || $dwelling->wall_color == $color) { // begin if
$output[] = $dwelling;
} // end if
} // end foreach
return $output; // return after the foreach has ended
Hope this helps!

13,672 PointsFantastic! Thanks so much Jennifer, I was so focussed on the conditional as the problem I missed the return statement.
