Default php.ini macOs Catalina

Question

I would like to know which php.ini is the default one used by PHP ?

Because if you write locate php.ini there a 3 files and all of these files have an /etc as parent directory, but not the same parent directory of /etc, so I don't know which one is the default one used by PHP. Terminal output

Answer 1

Type in your console:

php -i |grep php\.ini
