All those characters might be in a headline? If so, carry on. If not, it
would be worth finding out (using historical data or something) how you
can restrict your criteria a bit more.

I was going to say you might consider using ctype_digit(), but I guess
your use of "+" is a nice extra check. :-)

If 0 is not a valid value, you could always use ctype_digit() combined
with a simple conditional to ensure the value is > 0.
