Its an issue of extension directory. You need to change php extension directory manually to work this.
If you are using AMPP Server, do the following
Goto settings -> PHP -> Configuration
in php7.3.ini Find, (Versions might change)
extension_dir = "" , (Already having some path)
and change value to
extension_dir = "C:\Program Files\Ampps\php-7.3\ext"
If you are using XAMP
Goto XAMP Settings, Apache -> PHP.ini
Find, extension_dir = in php.ini, and set path of the php extension folder of your local machine. See the below example.
extension_dir = "C:\php\ext" (Check your path properly)
