I'm trying to understand this code, and when I arrived at the final line, I didn't get it. :(
Can I have your help in order to find out, what does return $this
mean ?
public function setOptions(array $options) {
$methods = get_class_methods($this);
foreach ($options as $key => $value) {
$method = 'set' . ucfirst($key);
if (in_array($method, $methods)) {
$this->$method($value);
}
}
//???? - return what ?
return $this;
}
Update:
I've removed my comments for better clarification.
