bitwise right shift is probably the fastest cast to int so far ... still in many languages, intval
is a function call
being a cast in both cases (int) is good as well ... bitwise, casting, works with strings, arrays,
boolean, whatever as well.
I don't think there is any difference in php, except when the integer is "too big"
... but this was not the case, we had to deal with 1 to 10 :-)
