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

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

+;   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

+;   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

+; Default Value: no

+
+; Limits the extensions of the main script FPM will allow to parse. This can

+

+; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.
+
+; Defining 'extension' will load the corresponding shared extension from

+
+; Note: path INI options can be relative and will be expanded with the prefix
