I need the permissions on :-
PHP >= 7.3
BCMath PHP Extension
Ctype PHP Extension
Fileinfo PHP Extension
JSON PHP Extension
Mbstring PHP Extension
OpenSSL PHP Extension
PDO PHP Extension
Tokenizer PHP Extension
XML PHP Extension

How can I make on? Please help me in this regard. Thanks

apt update
apt install php7.3-EXTENSIONNAME

But I think all mentioned extensions are already installed by default.
