(PECL pecl_http:0.1.0-1.5.5)
http_redirect — Issue HTTP redirect
Description
void http_redirect
([ string $url
[, array $params
[, bool $session = FALSE
[, int $status
]]]] )
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 setting
http.log.redirect is set and the redirect attempt was successful.
