.htaccess remove PHP extension

# Remove .php extension
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\ (.*)\.php [NC]
RewriteRule ^ %1 [R=301,NE,L]

# Check whether the file exists then set it back internally
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^.*$ $0.php [L,NE]


## Notes:
## [NE] - NotEscape flag is needed so the redirect works with UTF8 URLs (eg. Chinese character)
## The first block removes the .php extension, the second one serves the correct file when the extension is missing
## ^[A-Z]{3,}\ - Skips the POST or GET method from the HTTP request (THE_REQUEST)
