[FX.php List] php 5 problems: I have tried to copy my existing scripts to php5 enabled servers

[Carl Anderson]

Error, or warn?  I'm using it now, and I believe we're running 5 in-house,
but I haven't seen anything bomb.

(Mind you, most of what my $var happens to be is $_POST stuff anyhow, so
it's pretty well guaranteed to be set, by me.)
