After upgrading from PHP 5.6 -> 7.2, when index.php is accessed, the contents of the file are displayed on the screen, how can I fix it?

Question

linux

Installed php 7.2 on the server, specified
upstream php in Nginx config
{
server unix:/var/run/php/php7.2-fpm.sock;
}
Reloaded Nginx and when you go to the site, the contents of the index.php file are displayed on the screen, what's the matter? If you write
server unix:/var/run/php/php5.6-fpm.sock; then the problem goes away, and the Html template is loaded from the directory on the server, where to dig? Do you really need to reconfigure some Nginx rules for Php 7.2, or maybe the error lies in the fact that the script was written for PHP 5.6 and was never tested for 7.2, but it doesn’t introduce any errors either.

Answer 1

Maybe short tags <? ?>, which are disabled in the config for 7.2

Answer 2

I also displayed at first if you have centos 6 or 7
then there is php.conf in the /etc/httpd/php-available.d folder
, and there is also probably a php.conf.new file, change it to php.conf, keeping the old one your version
should be something like here
