301 or 302 Redirection With PHP
For a 302 Found, i.e. a temporary redirect do:
header('Location: http://www.example.com/home-page.html');// OR: header('Location: http://www.example.com/home-page.html', true, 302);exit;If you need a permanent redirect, aka: 301 Moved Permanently, do:
header('Location: http://www.example.com/home-page.html', true, 301);exit;For more info check the PHP manual for the header function Doc. Also, don't forget to call exit; when using header('Location: ');
But, considering you are doing a temporary maintenance (you don't want that search engines index your page) it's advised to return a 503 Service Unavailable with a custom message (i.e. you don't need any redirect):
<?phpheader("HTTP/1.1 503 Service Unavailable");header("Status: 503 Service Unavailable");header("Retry-After: 3600");?><!DOCTYPE html><html><head><title>Temporarily Unavailable</title><meta name="robots" content="none" /></head><body> Your message here.</body></html>
The following code will issue a 301 redirect.
header('Location: http://www.example.com/', true, 301);exit;
I don't think it really matters how you do it, from PHP or htaccess. Both will accomplish the same thing.
The one thing I want to point out is whether you want the search engines begin to index your site in this "maintenance" phase or not. If not, you could use the status code 503 ("temporarily down"). Here's a htaccess example:
RewriteEngine onRewriteCond %{ENV:REDIRECT_STATUS} !=503RewriteCond %{REMOTE_HOST} ^192\.168\.0\.1ErrorDocument 503 /redirect-folder/index.htmlRewriteRule !^s/redirect-folder$ /redirect-folder [L,R=503]In PHP:
header('Location: http://www.yoursite.com/redirect-folder/index.html', true, 503);exit;With the current PHP redirect code you're using, the redirect is a 302 (default).
