HTTP 301 Redirect is an SEO friendly way to redirect readers to a page’s new location. There are a lot of benefits of using HTTP 301 Redirect. These benefits can be found in the htaccess method post. htaccess or PHP can be both used for sending 301 redirects. The htaccess method can be found in How to Redirect Old Domain to New Domain Using htaccess Redirect. This post discusses the method that use php to generate the HTTP 301 Redirect.
As an example, we will redirect a page to https://www.systutorials.com in PHP.
<?php // Permanent 301 redirection header("HTTP/1.1 301 Moved Permanently"); header("Location: https://www.systutorials.com/"); exit(); ?>
<?php header("Location: https://www.systutorials.com/", true, 301); exit(); ?>
The header("HTTP/1.1 301") part must be used before the location part, otherwise PHP will automatically set the status code to HTTP/1.1 302 Found.
