title: PHP_VALUE in nginx.conf doesn't override parameters in php.ini
body: <p>I have this location section in nginx.conf:</p>
  
  <pre><code>location ~ \.php {
              try_files $uri =404;
              fastcgi_split_path_info ^(.+\.php)(/.+)$;
              include fastcgi_params;
              fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
              fastcgi_param   PHP_VALUE   "memory_limit = 500M; post_max_size = 400M; upload_max_filesize = 300M";
              fastcgi_param SCRIPT_NAME $fastcgi_script_name;
              fastcgi_index index.php;
              fastcgi_pass 127.0.0.1:9000;
  }
  </code></pre>
  
  <p>I need to increase these parameters for file downloading, but there're still previous values of php.ini in <code>phpinfo()</code>-list, despite updated  $_SERVER['PHP_VALUE'] (contains values written by me in the config). I'd tried to change values in different ways: without semicolon, with <code>\n</code>, mixed both the previous variations, replaced <code>PHP_VALUE</code> with <code>PHP_ADMIN_VALUE</code>, copied the param from others' config; but it still was unsuccessful. Where's the problem? What obstruct to apply my params?</p>
