Re: Warning is right or not ?

[RichardK]

Did you really intent to put a comma in this, or is it a typo?

return $data[$count-1],"\n";

As it is, this will only return "\n"

That is typo, because there was print before return to test that line, thank you for pointing that out. And when I removed that, the warning disappeared too, thank you very much :)
