Why does deleting .php remove request data?

Question

htaccess

Making a request to example.com/script?data=123

$_REQUEST is missing any data

My .htaccess

RewriteEngine On
RewriteCond %{THE_REQUEST} " (/[^?/]+)\.php"
RewriteRule ^ %1 [R=301,L]

RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^([^/]+)$ /$1.php$2 [L]

How can this be fixed?

Answer 1

scored on $_REQUEST began to read through $_SERVER["REQUEST_URI"]
