我正在嘗試使用類似于 Rot13 的算法在 PHP 中對字符串進行編碼，然后在 JavaScript 中對字符串進行解碼并進行搜索和替換。它適用于 ASCII 字符，但不適用于 Unicode。我弄亂了附加的代碼，但無法讓它工作。<?phpfunction strRot($str, $n) { $len = mb_strlen($str); $min = 0; $max = 99999999; $final = ''; for ($i = 0; $i < $len; $i++) { $current = mb_ord($str[$i]); $val = $current+$n; if ($val >= $max) { $val = $val - $max; } if ($val <= $min) { $val = $val + $min; } $final .= mb_chr($val); } return $final;}?><!doctype html><html><head> <!-- Required meta tags --> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <!-- Bootstrap CSS --> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.2.1/css/bootstrap.min.css" integrity="sha384-GJzZqFGwb1QTTN6wy59ffF1BuGJpLSa9DkKMp0DgiMDm4iYMj70gZWKYbI706tWS" crossorigin="anonymous"> <title>Hello, world!</title></head><body> <h1>Hello, world!</h1> <h2>ü and ?. 棕色的狐貍跳了起來.</h2> <p>The Hello, world! expression will be replaced.</p> <p>ü and ?. 棕色的狐貍跳了起來.

如果包含 Unicode 字符，則無法在 JavaScript 中解碼 PHP 中的編碼字符串
