Calling Methods on an Object Returned by Another Method (PHP Cookbook)

7.7. Calling Methods on an Object Returned by Another Method

$orange = $fruit->get('citrus');
$orange->peel( );

This is necessary because a parse error results from:

$fruit->get('citrus')->peel( );

Zend Engine 2 supports direct dereferencing of objects returned from a method so this workaround is no longer necessary.
