I wrote a short function to convert the hex string back to binary.


function hex2bin($data) {

$len = strlen($data);
for($i=0;$i<$len;$i+=2) {
$newdata .= pack("C",hexdec(substr($data,$i,2)));
}
return $newdata;
}

function hex2bin($data) {

$len = strlen($data);

return pack("H" . $len, $data);

}

Another one:

function hex2bin($hex_data){

return (DecBin(HexDec($hex_data));

}

echo bin2hex("abc");

Output is:
