php DomDocument-＆gt; saveHTML删除斜杠

Question

让我感到困惑的是：

<?php
echo "Start\n";
$newdoc = new DOMDocument();
$newdoc->loadHTML("<script>document.write('</scr' + 'ipt>');</script>");    
echo $newdoc->saveHTML();
echo "\nDone\n";

将输出：

<script>document.write('' + 'ipt>');</script>

为什么会这样做，我该如何避免呢？

Answer 1

你必须逃避斜线：

$newdoc->loadHTML("<script>document.write('<\/scr' + 'ipt>');</script>");
