Problem
Imagine that you have a StdClass (possibly created by a json_decode) instance full of attributes you want to retrieve. So you do something like this:
$username = $photo->owner->username;
What happens if username is undefined and/or owner?
$username = isset($photo) && isset($photo->owner) && isset($photo->owner->username)
? $photo->owner->username
: 'anonymous';
Imagine this kind of logic spread all over your codebase. What a mess!
Solution
Selector turns the horrible code above into this:
$photoSelector = Selector($photo);
$username = $photoSelector->getOne('owner.username', 'anonymous');
You never have to worry again about checking if the StdClass have the properties you need, and as a plus you receive several ways of retrieving data.
