Trait for making protected/private attributes "gettable", leaving "setting" the attributes a matter of business logic to be implemented.
<?php
trait Gettable {
/**
* Retrieve private attributes.
* Attributes should be protected
* so they cannot be *set* arbitrarily.
* This allows us to *get* them as if they
* were public.
* @param String $key
* @return mixed
*/
public function __get($key)
{
if( property_exists($this, $key) )
{
return $this->$key;
}
}
}
