Nginx cannot parse the php page, status is 200, and there is nothing in the error log,

but the html page can be parsed smoothly.

cenos7 system version, Nginx version is 1.14. Basically all the methods on the Internet have been tried, but it is useless to add fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name to nginx.conf.

my nginx.conf content:

user  root;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  "$remote_addr - $remote_user [$time_local] "$request" "
                      "$status $body_bytes_sent "$http_referer" "
                      ""$http_user_agent" "$http_x_forwarded_for"";

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    -sharptcp_nopush     on;

}
