5. }
6. function closeUnclosedTags($html) {
7.     $dom = new DOMDocument();
8.     @$dom->loadHTML($html);
10.     // Get the body element

php自动关闭HTML标签？

測試：

上面的代码的innerHTML函数 参考了stackoverflow.com/questions/2087103/how-to-ge … innerhtml-of-domnode

再试一下 未关闭的html标签：

1. $html = 'Unclosed iframe test: <iframe';
3. echo closeUnclosedTags($html);

Copy the Code

<p>Unclosed iframe test: <iframe></iframe></p>
看起来成功了
