Hi Ralph
I was about to ask the same thing, but your explanation makes
complete sense.
Should we take this as another unofficial coding standard that these
magic methods should all be protected (except __construct, of course,
for where it needs to be public)?
The reason it was made protected was to prevent the masses from
using the __get()/__set()/__isset()/__unset() methods directly, as
that usage is frowned upon.. ie: $session->__get($name);
The reason is to protect from unintentional misuse. As this scenario:
$session = new Zend_Session();
$var = array('foo'=>'bar');
$session->__set($var, 'value');
Would produce unexpected results.
