How to load PHP file without using .php extension

Question

I am using this code to load the PHP file without using php extension. It works good with localhost, but it gives error in live server.

RewriteEngine on

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^(.*)$ $1.PHP [NC,L]

I have also used this solution, but it does not work:

RewriteEngine on

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([0-9]+)/?$ test.php?id=$1 [L]

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^([^\.]+)$ $1.php [NC,L]

Answer 1

Always write the code at top of .htaccess

RewriteEngine on

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([0-9]+)/?$ test.php?id=$1 [L]

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^([^\.]+)$ $1.php [NC,L]
