.htaccess rewrite to redirect root URL to subdirectory

I need to change all the links(2455) in my site.

There will be a problem when visitors come from Google (using the old links) as the page will be 404 page not found

I want to redirect the old links to the new version of the page. For example:

Old links:

http://example.com/hotel/13234
http://example.com/hotel/132
http://example.com/hotel/323
http://example.com/page/about_us
http://example.com/page/contact

New links: (add “blog” ) after domain

http://example.com/blog/hotel/13234
http://example.com/blog/hotel/132
http://example.com/blog/page/about_us
http://example.com/blog/hotel/323

...
...
...

What is the best way to do this?

Answer 1

You can redirect them to the new Location with

header('Location: /blog' . $_SERVER['PHP_SELF']);

If you use PHP version >= 5.4.0, you can also send a proper HTTP status code 301 (moved permanently) with

http_response_code(301);

When you want to use .htaccess you can redirect with RewriteCond and RewriteRule.

RewriteEngine On
RewriteCond %{REQUEST_URI} !^/blog/
RewriteRule .* /blog$0 [L,R=301]

The RewriteCond directive prevents rewriting URLs, which already start with /blog. Otherwise you will get an endless recursion.
The RewriteRule directive prefixes all URLs with /blog, doesn’t apply further rules L and sends HTTP status code 301 R=301.

For this to work, these directives must be allowed in .htaccess. You can use the same directives in your main conf file or in a virtual host context.
