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.
Random\Randomizer::$engine 的
Random\Engine::generate() 方法抛出的任何 Throwable。
示例 #1 Random\Randomizer::shuffleBytes() example
<?php
$r = new \Random\Randomizer();
// Shuffle bytes in a string:
echo "«", $r->shuffleBytes("PHP is great!"), "»\n";
?>以上示例的输出类似于：
« ga rHs!PPiet»
示例 #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";
?>以上示例的输出类似于：
Original: 🍎, 🥝, 🍌, 🍑, 🍇 Shuffled: «� ��,�����🍟,� �� �, �,��» Shuffled Bytes: 87208e912c8d9fa5f0f0f09f8d9f2cf09f208c9d20f02c209f2c8d8d
