Answer 1

I’m not 100% sure what that Java code does, but it looks equivalent to something like this:

$tempByte = "\x01\x01";

“Byte arrays” are essentially strings in PHP, or rather “strings” are essentially byte arrays in PHP. You can even access this “byte array” using the array offset syntax:

echo bin2hex($tempByte[0]);
