  ; Default Value: daemon

  ; FPM can handle. Your system will tell you anyway :)
  
  ; Include one or more files. If glob(3) exists, it is used to include a bunch of

  ; By default the status page output is formatted as text/plain. Passing either

  ; Redirect worker stdout and stderr into main error log. If not set, stdout and
  ; stderr will be redirected to /dev/null according to FastCGI specs.
  ; Note: on highloaded environement, this can cause some delay in the page
  ; process time (several ms).
  ; Default Value: no
  ;catch_workers_output = yes
  
  ; Clear environment in FPM workers
  ; Prevents arbitrary environment variables from reaching FPM worker processes
  ; by clearing the environment in workers before env vars specified in this
  ; pool configuration are added.
  ; Setting to "no" will make all environment variables available to PHP code
  ; via getenv(), $_ENV and $_SERVER.
  ; Default Value: yes
  ;clear_env = no
  
  ; Limits the extensions of the main script FPM will allow to parse. This can
  ; prevent configuration mistakes on the web server side. You should only limit
  ; FPM to .php extensions to prevent malicious users to use other extensions to
  ; execute php code.
  ; Note: set an empty value to allow all extensions.
  ; Default Value: .php
  ;security.limit_extensions = .php .php3 .php4 .php5 .php7
  
  ; Pass environment variables like LD_LIBRARY_PATH. All $VARIABLEs are taken from

  ; Additional php.ini defines, specific to this pool of workers. These settings
  ; overwrite the values previously defined in the php.ini. The directives are the
  ; same as the PHP SAPI:
  ;   php_value/php_flag             - you can set classic ini defines which can
  ;                                    be overwritten from PHP call 'ini_set'.
  ;   php_admin_value/php_admin_flag - these directives won't be overwritten by
  ;                                     PHP call 'ini_set'
  ; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.
  
  ; Defining 'extension' will load the corresponding shared extension from
  ; extension_dir. Defining 'disable_functions' or 'disable_classes' will not
  ; overwrite previously defined php.ini values, but will append the new value
  ; instead.
  
  ; Note: path INI options can be relative and will be expanded with the prefix
  ; (pool, global or /usr)
