Answer 1

你可以试试这样的

<?php
$strWithHTML="<p>he adventures <p>
<p>of < span >adolescence< /span > had taught Piet < span >Barol< /span > that he</p>";

$strWITHOUTHTML=str_replace(array('< ','/',' >','span'),'',strip_tags($string1));

我想要结果将我 HTML 格式

<?php
$strWithHTML="<p>he adventures <p>
<p>of < span >adolescence< /span > had taught Piet < span >Barol< /span > that he</p>";

echo htmlentities($strWithHTML);
