I have a PHP web application that does work in my local Apache development environment. However, the same app does not work in my production environment with nginx (1.4.6/Ubuntu) and PHP-FPM. When I use PHP header in my development environment, the client gets a 302 and is redirected to the appropriate page. However, the same function call serves the client with a 200 response in nginx PHP-FPM.

public static function redirect($path = '') { //I call this function with $path='dashboard'
    $location = 'Location: ' . Settings::getConfig()['url'] . $path;
    //var_dump($location); die; // If I leave this line for debugging, this line outputs that $location is a string, and has value 'Location: http://[myDomain]/dashboard'
    header($location); //after this line, nginx sends a 200 back to the client, while Apache (correctly) sends a 302.
}

The end result is that clients are not able to login in my production environment. What could be the possible cause of this problem?

Excerpt of my nginx configuration:

fastcgi_buffers 16 16k;
fastcgi_buffer_size 32k;

server {

listen 5001 default_server;
listen [::]:5001 default_server ipv6only=on;
root /var/www/[domain]/public/;
index index.php index.html index.htm;
server_name [domain];


location /uploads {
            try_files $uri $uri/ =404;
    }

    location /assets {
            try_files $uri $uri/ =404;
    }
location / {
    try_files $uri $uri/ /index.php?$query_string;
    rewrite ^/(.*)$ /index.php?url=$1 last;
}

location ~ .php$ {

    fastcgi_split_path_info ^(.+.php)(/.+)$;
    fastcgi_index index.php;
    fastcgi_pass unix:/var/run/php/php7.0-fpm-01.sock;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_param SCRIPT_NAME $fastcgi_script_name;

  • What in your PHP code causes this redirect() function to be executed? You should also always be exit or dieing after a Location header. Otherwise, subsequent PHP code will still execute, so if there's something else in your code that sends a 200 response, that'll do it. – ceejayoz Mar 15 '18 at 13:40
  • Upon a successful verification of login credentials, the user is redirected to the application dashboard. It's tempting to do a PHP hack to fix this (I've already tried die/exit and it doesn't work), but I've been given this application and been tasked to make it work in nginx as it does in Apache. – Magnus Mar 15 '18 at 13:53
  • What is sitting in front of nginx? – Michael Hampton Mar 15 '18 at 16:55
  • Again, what is sitting in front of nginx? – Michael Hampton Mar 15 '18 at 21:41
  • Sorry for my hours of absence. I'm not a sysadmin and not 100% sure what you're asking, but nginx is not used as a proxy load balancer for Apache etc. My stack consists of Ubuntu 14, nginx 1.4.6/Ubuntu, MySQL and PHP 7.0 with PHP-FPM. – Magnus Mar 15 '18 at 22:37

Your function works on nginx/1.13.8 with PHP7.0

nginx configuration (default)

location / {
    # First attempt to serve request as file, then
    # as directory, then fall back to displaying a 404.
    try_files $uri $uri/ =404;
}
location ~ \.php$ {
    include snippets/fastcgi-php.conf;
    fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
}

/etc/nginx/snippets/fastcgi-php.conf (default)

fastcgi_split_path_info ^(.+\.php)(/.+)$;
try_files $fastcgi_script_name =404;
set $path_info $fastcgi_path_info;
fastcgi_param PATH_INFO $path_info;
fastcgi_index index.php;
include fastcgi.conf;
  • It should have been clearer in my post, but that var_dump is only there for debugging purposes. I've corrected it. Moreover, apache runs this fine, while my nginx php-fpm stack does not. I wish I could fix the issue by changing the configuration files instead of the code. – Magnus Mar 15 '18 at 14:22

    Does nginx give you the Location response header with the 200 OK ? – Gerard H. Pille Mar 15 '18 at 14:57
  • No, the location header isn't there. Can there even be a location header in HTTP 200? – Magnus Mar 15 '18 at 15:02

    So, your redirect function is never called? Did you check the error logs? Clear your browser cache? – Gerard H. Pille Mar 15 '18 at 15:10

    I've tested your function with nginx/1.13.8 and Apache 2.4.35 on Linux Devuan, and no matter if the header comes before the var_dump or not, I get a 302. I'll add my nginx default.conf to my answer. – Gerard H. Pille Mar 15 '18 at 19:48
