How can I hide folder name from URL using .htaccess

Question

I have a website with the root folder 'www', but I put all php files including index.php in a sub-folder of root. I wrote myself a .htaccess file to redirect, so if I input www.test.com , it will jump to www.test.com/folder and display the index.php .

Below it's my .htaccess which I put in the root.

 RewriteEngine On
 RewriteBase /
 RewriteRule ^folder2 - [L] 
 #ignore folder2 in which I put important files, but no works for the website
 RewriteCond %{REQUEST_URI} !^/folder(.*)
 RewriteRule (.*) /folder/$1

Right now, I want to change the .htaccess file to reach these goals:

1. When I input www.test.com , jump to www.test.com/folder as usual, but display the url without folder .

2. All the pages in folder will display the url without folder name. Such as

   www.test.com/shop/page1 -> www.test.com/page1

I searched some of the scripts, but none of them works.

I've found this related question which answers to your problem. The snippet from the answer is (note: it's adjusted to your needs):

RewriteEngine On
RewriteBase /

RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/+folder/([^\s]+) [NC]
RewriteRule ^ %1 [R=301,L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule (?!^folder/)^(.*)$ /folder/$1 [L,NC]

You can use below code.

RewriteEngine On
RewriteBase /
RewriteRule ^/?$ /folder/ [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /folder/$1 [L]

Answer 3

Based on your current rules. You can just make a slight adjustment.

 RewriteEngine On
 RewriteBase /
 #ignore folder2 in which I put important files, but no works for the website
 RewriteRule ^folder2/? - [L] 

 RewriteRule ^/?$ /folder/ [L]
 RewriteCond %{REQUEST_FILENAME} !-f
 RewriteCond %{REQUEST_FILENAME} !-d
 RewriteRule ^(.*)$ /folder/$1 [L]
