Errors “Undefined variable” and “Uninitialized string offset”

There is a code with errors, you need to fix it. The code is only 1 page. I can’t show it here, because. I bought it and therefore I will violate copyright.

PHP Notice: Undefined variable: nxt in


PHP Notice: Uninitialized string offset: 0 in

You may also find other errors.

Answer 1, authority 100%

I think it’s enough to insert at the beginning of the script

$nxt = '';

This will explicitly state that the variable exists before using it.

Answer 2, authority 33%

Notice is not an error, an error is not a warning. In general, I advise you to contact the author, because it’s not good to sell code of this quality.
