Lorem Ipsum只是印刷和排版行业的虚拟文本。自16世纪以来，Lorem Ipsum一直是行业标准的虚拟文本，当一个不知名的印刷商拿着一个铅字厨房，把它拼凑成一个铅字样品 有人知道怎么做吗？希望你能理解这个问题。提前谢谢。

用正则表达式解析/转换HTML内容不是个好主意。
但对于您的小片段，并考虑到您需要在删除自身时保留链接文本（例如，

“Lorem Ipsum”

），您可以使用以下

preg\u replace

解决方案：

$html = '<a href="http://www.lipsum.com/">Lorem Ipsum</a> is simply dummy text 
of the printing and typesetting industry. 
<a href="http://www.google.com/1111/2222/3333">Lorem Ipsum</a> has been the industrys 
standard dummy text ever since the 1500s, when an unknown printer 
took a <a href="http://gallery.com">galley</a> of type and scrambled 
it to make a type specimen <a href="http://www.google.com/1111/3333/4444">book</a>.';

$re = '/<a href="http:\/\/(?!www\.google\.com\/1111\/3+\/[^>]+).*?>([^<>]+)<\/a>/m';
$result = preg_replace($re, "$1", $html);

echo $result;

输出：
