    function prefix_functionname() {

       somefunc(prefix_functionname_helperfunctionname($arg1, $arg2));
    }

    function prefix_functionname() {
       if (!function_exists('prefix_functionname_innerfunctionname')) {
           function prefix_functionname_innerfunctionname($arg1, $arg2) {
               ;
           }
       }
       // Code here...
       somefunc(prefix_functionname_innerfunctionname($arg1, $arg2));
    }

    function prefix_functionname() {
       $innerfunctionname = function ($arg1, $arg2) {
           ;
       }
       // Code here...
       somefunc($innerfunctionname($arg1, $arg2));
    }

    function prefix_functionname() {
       function innerfunctionname($arg1, $arg2) {
           ;
       }
       // Code here...
       somefunc(innerfunctionname($arg1, $arg2));
    }

• Write little script that checks for the current use of nested functions in common frameworks like Symphony and Zend. I am assuming this is zero.
