//两层过滤，获取留言的内容
$str='<div id="read_111111" style="font-size:14px;line-height:150%;padding:10px;">测试文字1<div id="lwd_12223"><h6 class="quote"><span class="s3 f12 fn">楼主留言：</span></h6><blockquote class="blockquote">测试文字2..</blockquote></div></div>';
//$str='<div id="read_111111" style="font-size:14px;line-height:150%;padding:10px;">厉害</div>';
//preg_match("/[^.*](style=\"font-size:14px;line-height:150%;padding:10px;\">)(.*)<\/div>.*$/",$str, $str_arr);The above introduces the two-layer filtering of PHP to obtain the content of the message, including aspects of the content. I hope it will be helpful to friends who are interested in PHP tutorials.
