php `$_SERVER[‘PHP_SELF’]` is empty

I have a problem with my nginx and php configuration. For some reason, $_SERVER['PHP_SELF'] is empty.

I am running:

• Ubuntu 18.04
• nginx (nginx version: nginx/1.14.0 (Ubuntu))
• php (PHP 7.2.10-0ubuntu0.18.04.1)

I have no clue what may cause this issue. I’ve read a lot online but couldn’t find any solution.

Just to see if there’s more info missing, I checked what I’m getting from print_r($_SERVER);, here’s what I’m getting (Censored private info…):

Array ( [USER] => www-data [HOME] => /var/www [HTTP_COOKIE] => CENSORED [HTTP_ACCEPT_LANGUAGE] => en-GB,en;q=0.9,he-IL;q=0.8,he;q=0.7,en-US;q=0.6,ru;q=0.5 [HTTP_ACCEPT_ENCODING] => gzip, deflate, br [HTTP_ACCEPT] => text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,/;q=0.8 [HTTP_USER_AGENT] => CENSORED [HTTP_UPGRADE_INSECURE_REQUESTS] => 1 [HTTP_CACHE_CONTROL] => max-age=0 [HTTP_CONNECTION] => keep-alive [HTTP_HOST] => cumta.morhaviv.com [SCRIPT_FILENAME] => /var/www/morhaviv.com/public_html/cumta/css/test.php [REDIRECT_STATUS] => 200 [SERVER_NAME] => www.cumta.morhaviv.com [SERVER_PORT] => 443 [SERVER_ADDR] => 153.92.209.235 [REMOTE_PORT] => 22964 [REMOTE_ADDR] => 176.231.2.86 [SERVER_SOFTWARE] => nginx/1.14.0 [GATEWAY_INTERFACE] => CGI/1.1 [HTTPS] => on [REQUEST_SCHEME] => https [SERVER_PROTOCOL] => HTTP/1.1 [DOCUMENT_ROOT] => /var/www/morhaviv.com/public_html/cumta [DOCUMENT_URI] => /css/test.php [REQUEST_URI] => /css/test.php [SCRIPT_NAME] => /css/test.php [CONTENT_LENGTH] => [CONTENT_TYPE] => [REQUEST_METHOD] => GET [QUERY_STRING] => [PATH_INFO] => [FCGI_ROLE] => RESPONDER [PHP_SELF] => [REQUEST_TIME_FLOAT] => 1549710420.5126 [REQUEST_TIME] => 1549710420 )

My nginx.conf:

user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

events {
    worker_connections 768;
    # multi_accept on;
}

http {
    include        fastcgi_params;

    sendfile on;

    # server_tokens off;

    # server_names_hash_bucket_size 64;
    # server_name_in_redirect off;

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

    ##
    # SSL Settings
    ##

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
    ssl_prefer_server_ciphers on;

    ##
    # Logging Settings
    ##

    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;

    ##

    ##

    gzip on;

    # gzip_vary on;
    # gzip_proxied any;
    # gzip_comp_level 6;

    # gzip_http_version 1.1;
    # gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

    ##
    # Virtual Host Configs
    ##

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;
}

I’m aware that this question may lack some more info that is needed, but I really have no idea what else is important so please comment and I’ll add the missing information.

Thank you for your help!

Answer

Some tutorials on installing nginx server with php, insist on changing the php.ini file’s parameter cgi.fix_pathinfo, to 0.

So my solution was changing in the php.ini:

cgi.fix_pathinfo = 0 

to the default:

cgi.fix_pathinfo = 1

That’s it basically.

The solution was found thank’s to kenzotenma’s comment on his answer, with this link: https://www.nginx.com/resources/wiki/start/topics/examples/phpfcgi/
