If you found this project but think it's incomplete or doesn't meet your needs, try Property Access.

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.
