可以用 DOMDocument DOMDocument::loadHTML ()& DOMDocument::normalizeDocument ()方法。

<?php
    $html = '<div><p>The quick brown <a href="">fox jumps';

    $DDoc = new DOMDocument();
    $DDoc->loadHTML($html);
    $DDoc->normalizeDocument();

    echo $DDoc->saveHTML();
?>

输出:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd"> 
<html><body><div><p>The quick brown <a href="">fox jumps</a></p></div></body></html>

从那里,只是 substr & strpos 去掉你不想要的html,就像这样:

<?php
    $html = '<div><p>The quick brown <a href="">fox jumps';

    $DDoc = new DOMDocument();
    $DDoc->loadHTML($html);
    $DDoc->normalizeDocument();

    $html = $DDoc->saveHTML();

    # Remove Everything Before & Including The Opening HTML & Body Tags.
    $html = substr($html, strpos($html, '<html><body>') + 12);
    # Remove Everything After & Including The Closing HTML & Body Tags.
    $html = substr($html, 0, -14);

    echo $html;
?>

我会这样做:

删除该点之后的所有子节点
截断字符串
