Hi,
$u->emails[] = $e;
I would hazard a guess because $u->emails isn't a concrete object
(whereas $u->_emails is, but is private.) It's sort of a virtual
reference - PHP has no way of knowing that $u->emails actually
translates into _emails which is an array, if you see what I mean
(it's difficult to explain.)
But that does not work. I've managed to achieve similar result
using a
different setter in User
public function __set($name, $value)
{
$property = '_' . $name;
switch($name)
{
case 'emails':
array_push($this->$property, $value);
break;
default:
$this->$property = $value;
}
}
You could also have done:
if (is_array($this->$property))
{
array_push($this->$property, $value);
}
else
{
$this->$property = $value;
}
which would handle any array property, not just the e-mails property.
If this was me, I would probably create a concrete method, called
"addEmail" which would do $this->_emails[] = $value, but allow a
programmer to call $user->emails to get the e-mails (not set.)
