+      about possibls bugs in your code. For example, use of unassigned values
+      are warned. It is extremely useful to find typos and
+      to save time for debugging. NOTICE messages will warn you about bad style.
+      For example, $arr[item] is better to be written as $arr['item'] since
+      PHP tries to treat "item" as constant. If it is not a constant, PHP assumes
+      it is a string index for the array.

       setting there must be numeric; hence, it is <literal>7</literal>.
