Php configuration problems, phpinfo can be resolved, but others cannot. Ask for advice! -Php Tutorial

Php configuration problems, phpinfo can be resolved, but others cannot. Ask for advice! Ask a question: why can I parse phpinfo () after configuration, but cannot parse other PHP files. The source code is displayed. However For example:
Echo"

Order processed

"
;?>
Then display
Order processed
";?>
My httpd. conf setting is to change the phph and apache paths and add the Loadmodule and addtype statements.
Ask where the problem exists.
Thank you!

I used to open it directly, so I couldn't do it. I put it in htdocs and enter the localhost address in the browser.
