Why php is not executed, but the contents of the file are displayed on the screen?

Question

PHP

I set up a server on Centos7, the php content is displayed on the screen. How to win?

<IfModule php7_module>
    AddType application/x-httpd-php .php
    AddType application/x-httpd-php-source .phps
    <IfModule dir_module>
        DirectoryIndex index.html index.php
    </IfModule>
</IfModule>

This solution did not help
