$functionName = __FUNCTION__;
if ($functionName != ‘myFunction’) {

Javascript
function someFunc() {
var ownName = arguments.callee.toString();
ownName = ownName.substr(‘function ‘.length); // trim off “function ”
ownName = ownName.substr(0, ownName.indexOf(‘(‘)); // trim off everything after the function name
alert(ownName);
