Subject: Re: [PHP-DEV] ArrayPath
From: korvinszanto@gmail.com (Korvin Szanto)

In every project I have worked on in the last few years, I've
implemented this. If I have an array that I can't be sure is well
formed and need to get a value at any depth without triggering
expensive notices, the recommended way today is to check if each value
is set and is an array:
http://3v4l.org/23c9i

With this functionality, I can simply do:
array_get('key1.key2', 'default')
