    ; By default the status page output is formatted as text/plain. Passing either
    ; 'html', 'xml' or 'json' in the query string will return the corresponding
    ; output syntax. Example:
    ;   http://www.foo.bar/status

    ; By default the status page only outputs short status. Passing 'full' in the

    ;   http://www.foo.bar/status?json&full
    ;   http://www.foo.bar/status?html&full
    ;   http://www.foo.bar/status?xml&full

    ;   state                - the state of the process (Idle, Running, ...);
    ;   start time           - the date and time the process has started;
    ;   start since          - the number of seconds since the process has started;

    ;   request method       - the request method (GET, POST, ...);
    ;   request URI          - the request URI with the query string;
    ;   content length       - the content length of the request (only with POST);
    ;   user                 - the user (PHP_AUTH_USER) (or '-' if not set);
    ;   script               - the main script called (or '-' if not set);
    ;   last request cpu     - the %cpu the last request consumed
    ;                          it's always 0 if the process is not in Idle state
    ;                          because CPU calculation is done when the request
    ;                          processing has terminated;
    ;   last request memory  - the max amount of memory the last request consumed
    ;                          it's always 0 if the process is not in Idle state
    ;                          because memory calculation is done when the request
    ;                          processing has terminated;

    ; Note: chrooting is a great security feature and should be used whenever

    ; Clear environment in FPM workers
    ; Prevents arbitrary environment variables from reaching FPM worker processes

    ;                                     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/local/php7)
