Representation of an incoming, server-side HTTP request.

Per the HTTP specification, this interface includes properties for each of the following:

  • Protocol version
  • HTTP method
  • URI
  • Headers
  • Message body

Additionally, it encapsulates all data as it has arrived to the application from the CGI and/or PHP environment, including:

  • The values represented in $_SERVER.
  • Any cookies provided (generally via $_COOKIE)
  • Query string arguments (generally via $_GET, or as parsed via parse_str())
  • Upload files, if any (as represented by $_FILES)
  • Deserialized body parameters (generally from $_POST)

$_SERVER values MUST be treated as immutable, as they represent application state at the time of request; as such, no methods are provided to allow modification of those values. The other values provide such methods, as they can be restored from $_SERVER or the request body, and may need treatment during the application (e.g., body parameters may be deserialized based on content type).

Additionally, this interface recognizes the utility of introspecting a request to derive and match additional parameters (e.g., via URI path matching, decrypting cookie values, deserializing non-form-encoded body content, matching authorization headers to users, etc). These parameters are stored in an "attributes" property.

Requests are considered immutable; all methods that might change state MUST be implemented such that they retain the internal state of the current message and return an instance that contains the changed state.
