</a></div><p><a style="cursor:hand;" target="_blank" href="/d/f_players/4/3953/">阿扎尔</a></p>
</li>

</ul>
</div>

我想吧以上代码替换为空。简单点来说就是我要从<div class="pic-list">开始替换到与他匹配的</div>问题不清楚的可以追问

Answer 1

都帮你测试好了，正则多写一个<ul>就能搞定了：

<?php
$str = '你的一大堆字符串'; // 你如果直接放字符串，需要用单引号

$reg = '/<div class="pic-list">\s+<ul>.*?<\/ul>\s+<\/div>/is';

$new_str = preg_replace( $reg, '', $str);
echo $new_str;

?>

Answer 2

可以先把里面的div替换为空 再替换外面的
