php-v is executed by cli, and phpinfo is executed by web. It should be that the command line path of your cli is not updated.

as mentioned above, php-v is the php version of cli,phpinfo bound to your nginx or apache. Take nginx as an example

set different port numbers for different php-fpm, and use address plus port number as parameter at fastcgi_pass

find the libphp7.so path of php7.2
in the configuration file of apache, LoadModule php7_module modules/libphp7.so (here the path fills in the dynamic library path of 7.2)
then restart apache

< hr >

brew install php7.2 's fpm

I'll tell you how to switch php versions on mac
you see that phpinfo is seen on the web page, use php-fpm
to execute the command:
1.brew services stop php71
2.brew services start php72
