I suggest you to keep the text in link.
我建议您将文本保留在链接中。
strip_tags($text, '<br>');
or the hard way:
或艰难的方式：
preg_replace('#<a.*?>(.*?)</a>#i', '', $text)
If you don't need to keep text in the link
如果您不需要在链接中保留文本
preg_replace('#<a.*?>.*?</a>#i', '', $text)

While strip_tags()is capable of basic string sanitization, it's not fool-proof. If the data you need to filter is coming in from a user, and especially if it will be displayed back to other users, you might want to look into a more comprehensive HTML sanitizer, like HTML Purifier. These types of libraries can save you from a lot of headache up the road.
虽然strip_tags()能够进行基本的字符串消毒，但并非万无一失。如果您需要过滤的数据来自用户，特别是如果它会显示回其他用户，您可能需要查看更全面的 HTML 消毒剂，如HTML Purifier。这些类型的库可以让您免于头痛。
strip_tags()and various regex methods can't and won't stop a user who really wants to inject something.
strip_tags()并且各种正则表达式方法不能也不会阻止真正想要注入某些东西的用户。

this is my solutions :
这是我的解决方案：
function removeLink($str){
$regex = '/<a (.*)<\/a>/isU';
preg_match_all($regex,$str,$result);
foreach($result[0] as $rs)
{
$regex = '/<a (.*)>(.*)<\/a>/isU';
$text = preg_replace($regex,'',$rs);
$str = str_replace($rs,$text,$str);
}
return $str;}

One more short solution without regexps:
另一种没有正则表达式的简短解决方案：
function remove_links($s){
while(TRUE){
@list($pre,$mid) = explode('<a',$s,2);
@list($mid,$post) = explode('</a>',$mid,2);
$s = $pre.$post;
if (is_null($post))return $s;
}
}
?>
