Re: bit wise math? Is there a function to easily return the bits?

} (I wanted to see if I could write it in few LOC.) I wonder if there's a faster way... jon blackwater dev wrote:

Is there a php function I can call to pass in a number and get the values returned? For example, pass in 7 and get 1,2,4 ? Thanks!

and for those of us running PHP<5.x here is a working example

function bits($num) { $bit_array = split('.',strrev(decbin(intval($num)))); $val_array = array(); foreach ($bit_array as $pow => $bit) { if ($val = $bit * pow(2,$pow)) $val_array[] = $val; } return $val_array; } -- Enjoy, Jim Lucas Different eyes see different things.
