Random\Randomizer::shuffleBytes — Get a byte-wise permutation of a string
Returns a uniformly selected permutation of the input bytes.
Each possible permutation of the input bytes is equally likely to be returned.
A permutation of the bytes of bytes.

Приклад #1 Random\Randomizer::shuffleBytes() example

Приклад #2 Byte-wise shuffling breaks Unicode characters
<?php
$r = new \Random\Randomizer();
$unicode = "🍎, 🥝, 🍌, 🍑, 🍇";
$shuffled = $r->shuffleBytes( $unicode );
// Byte-wise shuffling of non-ASCII characters destroys them,
// resulting in invalid sequences (indicated by the Unicode
// replacement character) or even entirely different characters
// appearing in the output.
echo "Original: ", $unicode, "\n";
echo "Shuffled: «", $shuffled, "»\n";
echo "Shuffled Bytes: ", bin2hex($shuffled), "\n";
