Are you sure the iterator is never empty, otherwise this variable is not defined? It seems like you are relying on a variable being defined by an iteration: foreach ($a as $b) { } // $b is defined here only if $a has elements, for example if $a is array() // then $b would not be defined here. To avoid that, we recommend to set a // default value for $b. // Better $b = 0; // or whatever default makes sense in your context foreach ($a as $b) { } // $b is now guaranteed to be defined here.
