Nothing really wrong with the code, just different error reporting set.
But, as a couple of cents worth from someone that's learnt the hard way, it is
usually preferable to do something like
if (!isset($submit)){...} and handle the negative condition first. (Of course
this won't be the case if you know that the variable is set and could contain
a value of true (>0) or false (0).)
