When returning values, to return a custom status, you may return an
array with a status key.
Example 684. Returning Custom Status
<?php
/**
* Say Hello
*
* @param string $who
* @param string $when
* @return array
*/
function sayHello($who, $when)
{
return array('msg' => "An Error Occurred", 'status' => false);
}
$server = new Zend_Rest_Server();
$server->addFunction('sayHello');
$server->handle();
