Also, for those who wish to do bitwise shifting, it's quite simple.. to shift left, just
multiply the number by pow(2,x), and to shift right, divide by pow(2,x).
<?php
function gmp_shiftl($x,$n) { // shift left
return(gmp_mul($x,gmp_pow(2,$n)));
}
function gmp_shiftr($x,$n) { // shift right
return(gmp_div($x,gmp_pow(2,$n)));
}
?>
Nitrogen.
