REST Web Services use service-specific XML formats. These ad-hoc standards mean that the manner for accessing a REST web service is different for each service. REST web services typically use URL parameters (GET data) or path information for requesting data and POST data for sending data. Zend Framework provides both Client and Server capabilities, which, when used together allow for a much more "local" interface experience via virtual object property access. The Server component features automatic exposition of functions and classes using a meaningful and simple XML format. When accessing these services using the Client, it is possible to easily retrieve the return data from the remote call. Should you wish to use the client with a non-Zend_Rest_Server based service, it will still provide easier data access. In addition to Zend_Rest_Server and

Namespaces A subject touched and trialed many times in PHP, namespaces. This feature has been responsible for the longest discussions on PHP-DEV, but finally a consensus has arrived on how this is going to work. The biggest benefit namespaces will provide is shortening of long classnames. To make sure that your class libraries can plug into foreign code, it has always been recommended to prefix your classes, for example "Zend_DB_Connection". This can however lead to very long names. Namespaces fixes this by grouping classes together. The full-on classname becomes Zend::DB:Connection, and by placing 'use Zend::DB' on top of your code, the 'Connection' class can be referenced with just that name. Example: // The class file namespace Zend :: DB ; class Connection { function foo () { echo 'bar' ; } } ?> require 'Zend/DB/Connection.php' ; use Zend :: DB :: Connection ; $connection = new Connection (); $connection -> foo (); ?
