When you click on the link above, you are automatically redirected to this page. If you would like to notify search engines that a page has been permanently moved to another location, use the following code: įor example, this page has the following code: This means that search engines, such as Google Search, will not take the redirection into account when indexing. This means that no characters should ever be sent before the header - not even an empty space!īy default, the type of redirection presented above is a temporary one.

If ever the target page is on another server, you include the full URL: Īccording to HTTP protocol, HTTP headers must be sent before any type of content. When dealing with relative or absolute paths, it is ideal to choose an absolute path from the root of the server (DOCUMENT_ROOT).

This address can be absolute and may also include the parameters in this format: mypage.php?param1=val1&m2=val2) In this case, mypage.php is the address of the page to which you would like to redirect the visitors. To redirect the visitor to another page (particularly useful in a conditional loop), simply use the following code: I've also handled the issue of supporting the different HTTP redirection codes ( 301, 302, 303 and 307), as it was addressed in the comments of my previous answer. Header(sprintf('Status: %03u', $code), true, $code) Session_write_close() // Avoids having sessions lock other requests Session_regenerate_id(true) // Avoids session fixation attacks If (strlen(session_id()) > 0) // If using sessions I've already answered this question, but I'll do it again since in the meanwhile I've learnt that there are special cases if you're running in CLI (redirects cannot happen and thus shouldn't exit()) or if your webserver is running PHP as a (F)CGI (it needs a previously set Status header to properly redirect). Then you might use a HTML header workaround (not very professional!) like: They usually fail if invoked inmidst HTML output. $url, true, $statusCode) Īs mentioned header() redirects only work before anything is written out. This is more flexible: function redirect($url, $statusCode = 303)

This function doesn't incorporate the 303 status code: function Redirect($url, $permanent = false) You may use the alternative method of http_redirect($url) which needs the PECL package pecl to be installed. HTTP Headers and the header() function in PHP This is not true for many other user agents like spiders and robots. Currently used browsers are all HTTP/1.1 user agents. Note: W3C mentions that the 303-header is incompatible with 'many pre-HTTP/1.1 user agents. You should consider either 301 (permanent redirect) or 303 (other). PHP's 'Location'-header still uses the HTTP 302-redirect code, this is a 'temporary' redirect and may not be the one you should use. See RFC 7231 which had replaced the old RFC 2616, where only absolute URLs were allowed. Since June 2014 both absolute and relative URLs can be used. Why you should use die() or exit(): The Daily WTF You can use the header() function to send a new HTTP header, but this must be sent to the browser before any HTML or text (so before the declaration, for example).
