Why my module (rrd module) in phpinfo() is enabled but im still getting php error of "PHP Warning: PHP Startup: Unable to load dynamic library 'rrd'?

Question

I am using php v7.4, I just do what https://www.php.net/manual/en/rrd.installation.php says me to do but php cant see my php_rrd.dll file extension that I downloaded in PECL in C:\xampp\php\ext (my extension_dir is correct). When I do php -m I got a warning: Image of my error. but in my phpinfo() it appears that it is already enabled. When I tried to run my program in postman I got an error of "Attempted to call function "rrd_graph" from namespace "App\Service" which means that it cant still load my module that I installed. I am using XAMPP on windows. "
