http_redirect — Issue HTTP redirect
Redirect to the given url.
The supplied url will be expanded with http_build_url(), the params array will be treated with http_build_str() and the session identification will be appended if session is true. The HTTP response code will be set according to status . You can use one of the redirect constants for convenience. Please see » RFC 2616 for which redirect response code to use in which situation. By default PHP will decide which response status fits best.
To be RFC compliant, "Redirecting to <a>URL</a>." will be displayed, if the client doesn't redirect immediately, and the request method was another one than HEAD.
A log entry will be written to the redirect log, if the INI 设定 http.log.redirect is set and the redirect attempt was successful.
