Wrong. The offset is 4, the error message says so. Undefined offset means you are trying to access a character from a string that doesn't exist -- in this case, the 5th character of a string that is shorter than 5 characters. (If $myoffset was undefined, you'd get an undefined variable warning.) Cheers!
