Object-Oriented PHP Basics: I'm stuck at this function, don't know what is wrong, don't know how to proceed

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

Any help would be appreciated.

Many thanks.

try using foreach($this->houses as $house) PHP seems to need to be told that the variable is on the current object.

That fixed it for me :)

Thanks, Wayne you're right. That was the problem. It's working now.

Cheers.

Thanks, Simon, you're right.
