# http_redirect

(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` ]]]] )

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 setting http.log.redirect is set and the redirect attempt was successful.

### Parameters

`url`

  the URL to redirect to

`params`

  associative array of query parameters

`session`

  whether to append session information

`status`

  custom response status code

### Return Values

Returns `FALSE` or exits on success with the specified redirection status code. See the INI setting http.force_exit for what "exits" means.

### Examples

Example#1 A http_redirect() example

`<?php
http_redirect("relpath", array("name" => "value"), true, HTTP_REDIRECT_PERM);
