I need to throw a 404 and can do it like this:
throw new CHttpException(404, 'not found.');
but would prefer to use something like this:
throw new CHttpException(HTTPNotFound, 'not found.');
Is something like this already available in either Yii or PHP?
Not in the core, but you could very easily make your own class and steal the constants from Symfony.
protected/components/HttpStatus.php
<?php
class HttpStatus
{
const CONTINUE = 100;
const SWITCHING_PROTOCOLS = 101;
const PROCESSING = 102; // RFC2518
const OK = 200;
const CREATED = 201;
const ACCEPTED = 202;
const NON_AUTHORITATIVE_INFORMATION = 203;
const NO_CONTENT = 204;
const RESET_CONTENT = 205;
const PARTIAL_CONTENT = 206;
const MULTI_STATUS = 207; // RFC4918
const ALREADY_REPORTED = 208; // RFC5842
const IM_USED = 226; // RFC3229
const MULTIPLE_CHOICES = 300;
const MOVED_PERMANENTLY = 301;
const FOUND = 302;
const SEE_OTHER = 303;
const NOT_MODIFIED = 304;
const USE_PROXY = 305;
const RESERVED = 306;
const TEMPORARY_REDIRECT = 307;
const PERMANENTLY_REDIRECT = 308; // RFC7238
const BAD_REQUEST = 400;
const UNAUTHORIZED = 401;
const PAYMENT_REQUIRED = 402;
const FORBIDDEN = 403;
const NOT_FOUND = 404;
const METHOD_NOT_ALLOWED = 405;
const NOT_ACCEPTABLE = 406;
const PROXY_AUTHENTICATION_REQUIRED = 407;
const REQUEST_TIMEOUT = 408;
const CONFLICT = 409;
const GONE = 410;
const LENGTH_REQUIRED = 411;
const PRECONDITION_FAILED = 412;
const REQUEST_ENTITY_TOO_LARGE = 413;
const REQUEST_URI_TOO_LONG = 414;
const UNSUPPORTED_MEDIA_TYPE = 415;
const REQUESTED_RANGE_NOT_SATISFIABLE = 416;
const EXPECTATION_FAILED = 417;
const I_AM_A_TEAPOT = 418; // RFC2324
const UNPROCESSABLE_ENTITY = 422; // RFC4918
const LOCKED = 423; // RFC4918
const FAILED_DEPENDENCY = 424; // RFC4918
const RESERVED_FOR_WEBDAV_ADVANCED_COLLECTIONS_EXPIRED_PROPOSAL = 425; // RFC2817
const UPGRADE_REQUIRED = 426; // RFC2817
const PRECONDITION_REQUIRED = 428; // RFC6585
const TOO_MANY_REQUESTS = 429; // RFC6585
const REQUEST_HEADER_FIELDS_TOO_LARGE = 431; // RFC6585
const INTERNAL_SERVER_ERROR = 500;
const NOT_IMPLEMENTED = 501;
const BAD_GATEWAY = 502;
const SERVICE_UNAVAILABLE = 503;
const GATEWAY_TIMEOUT = 504;
const VERSION_NOT_SUPPORTED = 505;
const VARIANT_ALSO_NEGOTIATES_EXPERIMENTAL = 506; // RFC2295
const INSUFFICIENT_STORAGE = 507; // RFC4918
const LOOP_DETECTED = 508; // RFC5842
const NOT_EXTENDED = 510; // RFC2774
const NETWORK_AUTHENTICATION_REQUIRED = 511; // RFC6585
}
Then use it in code as:
throw new CHttpException(HttpStatus::NOT_FOUND, 'Not found.');
or you could define a constant in your components/controller.php
<?php
class Controller extends CController
{
const HTTPNotFound = 404;
// ...
}
// then in your controller you can do this
throw new CHttpException(self::HTTPNotFound, 'not found.');
Rather than copying constants I also prefer a centralizing class.

[size=2]Notes:[/size]
[size=2]1. "CONTINUE" as a constant lits up as an error in my editor because it corresponds to a reserved word (not that there is a real conflict, but it is better to avoid them).[/size]
class MyController extends CController implements HttpStatus
