sbτf¶☼╢ñ═∩p╙  _ë    ☺k ☺♦ Å☼♂↔☻        ♥

is there way me convert binary string of 0s , 1s?

this data not image , not text, small udp packages of data 0s , 1s have significance , need load data , interpret it

i couldn't find solution this, i'm going reinvent wheel bit.

function bindigitsfromstring($str) {     $r = '';     for($i=0; $i<strlen($str); $i++) $r .= sprintf("%08b",ord($str[$i]));     return $r; }
