+      variables</link> may be accepted. Use of this directive mitigates

+      If there are more input variables than specified by this directive,
+      an <constant>E_WARNING</constant> is issued, and further input
+      variables are truncated from the request. This limit applies only
+      to each nesting level of a multi-dimensional input array.
