Subject: Re: [PHP-DEV] The constant use of isset()
From: lewiswright@gmail.com (Lewis Wright)

Regarding ifsetor, what's wrong with just using this:

isset($myvar) OR $myvar =3D 'i am set';

It works in just the same way and has no problems. I agree it would be
great though if there could be a function to retrieve a variable's
value if it exists, without throwing an error if it doesn't exist. I'm
not sure if isset would be appropriate though.

Lewis.
