the print() stuff is minimal. You are just copying stuff to the buffer.
If you were outputting to a file when your way is faster.
It has to do with the fact that in the while you keep leaving the array.
and check the while, in the php layer.
In the foreach do the same thing just on the c layer. You save that bit
of time because you do not have to go out to the php engine and parse again.
