Do you know how to multiply extra-large numbers in PHP?


It seems that you really like our PHP Challenges, which really makes us happy. So we bring another one to your attention.

Since you got pretty comfortable with numbers during our last test, we will continue on testing your PHP skills with… numbers “management”.

So… what’s the result? And how long did it take to get this result?

Oh, and if you missed one of our previous challenges, you can find them here:
