The Apache Web server starts automatically after installation.
Appears in the lower right corner.
Apache has a default site directory after installation
Files in this directory can be accessed through the Web site on the browser.
After requesting localhost on the browser output, see this interface to indicate that Apache installation was successful.
Why do I have access to the files in the default directory?
is because DocumentRoot is configured in apache/conf/httpd.conf to point to the directory.
Now put a php file in the directory and visit the PHP file via the browser.
Why does this happen?
Because the Web server receives what files the browser needs, it sends the contents of the file to the browser display. The PHP code in the PHP file is not given to the PHP preprocessor for processing.
