I can see the phpinfo() information through http://localhost, but if I want to open it directly through the browser, the source code will be displayed.

Question

Answer 1

The path cannot be written like this in the environment 127.0.0.1 or localhost

Answer 2

Accessing the file directly through the browser will be treated as a text document, so the content of PHP will be displayed directly.

When accessed through the domain name, the result will be the content parsed by the PHP environment

Answer 3

PHP code must be implemented through the server. HTML can be opened directly like you do. PHP must be opened locally by entering localhost or 127.0.0.1 and the path/file name.
