$_SERVER['PATH_INFO'] will return /99. You could then use trim() or substr() to remove the /.

'PATH_INFO'
    Contains any client-provided pathname information trailing the actual script 
    filename but preceding the query string, if available. For instance, if the 
    current script was accessed via the URL 
    http://www.example.com/php/path_info.php/some/stuff?foo=bar, then 
    $_SERVER['PATH_INFO'] would contain /some/stuff.

from http://php.net/manual/en/reserved.variables.server.php

Update

Based on your comment, I'm a bit confused on what you are attempting exactly. If you are getting [object Object] back that means that you tried to send a JavaScript object as part of the URI. I would suggest using the HTTP Request body for any json data. If you intend to use the URI to uniquely identify the data you are sending to the server (like '99'), then the code above will help you to parse the URI. If you are wondering how to parse an HTTP request payload, then the following code will help.

Example POST request using json from the command line:

curl -i -X POST -d '{"a": 1, "b": "abc"}' http://localhost:8080/test/rdp3.php/99

Using PHP to parse the json object:

<?php
$data = json_decode(file_get_contents("php://input"));
var_dump($data); // $data is of type stdClass so it can be treated like an object.
var_dump($data->a); // => 1
var_dump($data->b); // => abcd

The URL is test/rdp3.php/99 is malformed.

What you would want to do is set a key and a value at the end of the url. So test/rdp3.php/99 would be test/rdp3.php?key=value. The ? denotes the beginning of the query string. Each key/value pair is then separated by &.

So you can have urls that look like this:

test/rdp3.php?key=value&id=99

Then in your PHP code to get the value of key you do:

$variableName = $_GET['key'];

To get the value of id you would do:

$variableName2 = $_GET['id'];
