Note Submitter: php at control-escape dot com ---- PHP functions that do not explicitly return a value will be 'void', that is, they return 'null'. C programmers will be accustomed to this already, but folks coming from Perl may expect the return value of a function to be the return value of the last expression evaluated inside the function, as is the case with Perl. Not so.
