undefined variables?!

[Anon]

One my friend has a bug message that he's variables are not defined. But we all know that PHP does not require variables to be defined. What can be the reason?

Is it possible that he adjast Perl instead of PHP tp have message?

Thank you

What he gets probably is a Warning message, right? You get that when a variable has not been set yet. You can avoid this by doing something like this before you really start using it: $VarName = "";

If you don't do that, 'if' statements like "if $VarName == 'moo'" will give that warning. Nothing serious, just annoying.

Although you should really define all your variables at some point before using them, it isn't a requirement. It's just bad coding practice not to.
