js: var l = 128, o = (z.length) / 2, = ''; (a = ((k - 1) * l); < ((k) * l); a++) += string.fromcharcode(z.slice(a * 2, (a + 1) * 2)); php : .... ?

thanks helps pros

i solved myself

first loop :

$z="..........."; // string $st1=",-+@/. ;_"; $st2="ntj2m10ao"; for($a=0;$a<9;$a++) $z=str_replace($st1[$a], $st2[$a], $z);

second loop :

$l = 128; $o = (strlen($z)) / 2; $i = ''; ($a = (($k - 1) * $l); $a < ($k * $l); $a++) $i .= chr(substr($z,($a*2),2));

thanks @mawg , others
