Decimal to binary conversion, using BC Math. Note: this function is VERY slow if the decimal number is too big! <? function bc_decbin($dec_str) { if (strlen($dec_str)>0) { $bin_str = ''; do { if (((int)$dec_str[strlen($dec_str)-1] % 2) === 0) $bin_str .= '0'; else $bin_str .= '1'; $dec_str = bcdiv($dec_str, '2'); } while ($dec_str!='0'); return strrev($bin_str); } else return null; } ?> ----- Cristian www.CodeFlower.com
