Here is a function which will do the zero fill shift right bitwise operator (>>>) which I haven't found in php but Java/JavaScript do have. The resulting number is always positive unlike >>.  

function zeroFill($a, $(IMG:http://forum.php.pl/style_emoticons/default/cool.gif) {  
$z = hexdec(80000000);  
if ($z & $a) {  
$a >>= 1;
$a &= (~ $z);  
$a |= 0x40000000;  
$a >>= ($b-1);
} else {  
$a >>= $b;
}  
return $a;  
}
