Title: Updated example for reduce operations.

The reduce operation effectively makes the power sequence left associative and will therefore always yield the same answer. I've therefore swapped the operation by a simple string concatenation.

Also, ^ is the bitwise xor operation; use pow() for that or wait for [my ** operator](https://github.com/datibbaw/php-src/compare/pow-operator) to be merged :)
