preg_replace的问题

Question

This is a simple one :)

I have this line which works great:

$listing['biz_description'] = preg_replace('/<!--.*?--\>/','',$listing['biz_description']);

What is the proper regex to remove the html entity version?

This is the entities:

<!-- -->

I would just decode the html entities if you are happy with the preg_replace regex you already have... html_entity_decode As @ircmaxell mentioned, using regex for html parsing can be very painfull.

$str = "This is a <!-- test --> of the emergency &lt;!-- broadcast --&gt; system";
$str = preg_replace('/<!--.*?--\>', '' ,html_entity_decode($str));
echo $str;
