当人们访问我的域时，它会使用 php 代码重定向到http://www.mydomain.com/en/index.php。我 在 .htaccess 中添加了以下代码
RewriteEngine on
Options +FollowSymlinks
RewriteBase /
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/ [R=301,L]
RedirectPermanent /pages/abc-123.html http://www.mydomain.com/en/page-a1/abc.php
to redirect people from non www to www,
将人们从非 www重定向到 www，
Still users can access by typing both http://mydomain.com/en/page-a1/abc.phpand http://www.mydomain.com/en/page-a1/abc.phpURLs
仍然用户可以通过输入http://mydomain.com/en/page-a1/abc.php和http://www.mydomain.com/en/page-a1/abc.phpURL来访问
Does anyone know the method to completely redirect to http://www.mydomain.com/en/page-a1/abc.phpeven if user typed http://www.mydomain.com/en/page-a1/abc.php, and prohibit accessing URLs without www.

if (substr($_SERVER['HTTP_HOST'], 0, 4) !== 'www.') {
header('Location: '.$protocol.'www.'.$_SERVER['HTTP_HOST'].'/'.$_SERVER['REQUEST_URI']);

I'm not sure how to do it through .htaccess, but I do it with PHP code myself within my config.phpwhich is loaded for every file.
我不确定如何通过 .htaccess 执行此操作，但我自己在config.php为每个文件加载的PHP 代码中执行此操作。
if(substr($_SERVER['SERVER_NAME'],0,4) != "www." && $_SERVER['SERVER_NAME'] != 'localhost')
header('Location: http://www.'.$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']);
EDIT:@genesis, you are correct I forgot about https
编辑：@genesis，你说得对，我忘记了 https
Change
改变
header('Location: http://www.'.$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']);
to
到
header('Location: '.
(@$_SERVER['HTTPS'] == 'on' ? 'https://' : 'http://').
'www.'.$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']);

Add RewriteEngine Onbefore RewriteCondto enable your rewrite rules:
添加RewriteEngine OnbeforeRewriteCond以启用重写规则：
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/ [R=301,L]
And if you have https:
如果你有 https：
RewriteEngine On
RewriteRule .? - [E=PROTO:http]
RewriteCond %{HTTPS} =on
RewriteRule .? - [E=PROTO:https]
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ %{ENV:PROTO}://www.%{HTTP_HOST}/ [R=301,L]

I think you want to redirect the user instead of rewriting the URL, in that case use Redirector 'RedirectMatch` directive. http://httpd.apache.org/docs/2.3/rewrite/remapping.html#old-to-new-extern
我认为您想重定向用户而不是重写 URL，在这种情况下使用Redirect或 'RedirectMatch` 指令。http://httpd.apache.org/docs/2.3/rewrite/remapping.html#old-to-new-extern
