| 6 | * Representation of an incoming, server-side HTTP request. |
| 7 | * |
| 8 | * Per the HTTP specification, this interface includes properties for |
| 9 | * each of the following: |
| 10 | * |
| 11 | * - Protocol version |
| 12 | * - HTTP method |
| 13 | * - URI |
| 14 | * - Headers |
| 15 | * - Message body |
| 16 | * |
| 17 | * Additionally, it encapsulates all data as it has arrived to the |
| 18 | * application from the CGI and/or PHP environment, including: |
| 19 | * |
| 20 | * - The values represented in $_SERVER. |
| 21 | * - Any cookies provided (generally via $_COOKIE) |
| 22 | * - Query string arguments (generally via $_GET, or as parsed via parse_str()) |
| 23 | * - Upload files, if any (as represented by $_FILES) |
| 24 | * - Deserialized body parameters (generally from $_POST) |
| 25 | * |
| 26 | * $_SERVER values MUST be treated as immutable, as they represent application |
| 27 | * state at the time of request; as such, no methods are provided to allow |
| 28 | * modification of those values. The other values provide such methods, as they |
| 29 | * can be restored from $_SERVER or the request body, and may need treatment |
| 30 | * during the application (e.g., body parameters may be deserialized based on |
| 31 | * content type). |
| 32 | * |
| 33 | * Additionally, this interface recognizes the utility of introspecting a |
| 34 | * request to derive and match additional parameters (e.g., via URI path |
| 35 | * matching, decrypting cookie values, deserializing non-form-encoded body |
| 36 | * content, matching authorization headers to users, etc). These parameters |
| 37 | * are stored in an "attributes" property. |
| 38 | * |
| 39 | * Requests are considered immutable; all methods that might change state MUST |
| 40 | * be implemented such that they retain the internal state of the current |
| 41 | * message and return an instance that contains the changed state. |
