First, I created an alias to send all requests to a single php file (service.php).
AliasMatch /Beers/.* /var/www/www.liquidmirth.com/service.php
This sends all http://www.liquidmirth.com/Beers/* requests to service.php. Then, I created a generic service class. This grabs the method, id and the target object from the url, and uses reflection to invoke the appropriate method on a service class. The code for the service.php class is below.
$method = strtolower($_SERVER["REQUEST_METHOD"]);
$object = $_SERVER["REQUEST_URI"];
$object = substr($object, 1, strlen($object)-1);
$vars = explode("/", $object);
$object = $vars;
$id = $vars;
// echo "method ==> (".$method.")
// echo "object ==> (".$object.")
// echo "id ==> (".$id.")";
$method = new ReflectionMethod($object, $method);
echo $method->invoke(NULL, $id);
In the above code, the request is received, the Beer object is created and the get() method is invoked on that object with the id supplied as a parameter. So, when http://www.liquidmirth.com/Beer/1234 is requested. Beer->get(1234) is invoked.
Its that simple.
