麻烦在线的大神写一个可以同时验证这两个URL的正则: http://mp.weixin.qq.com/s?__biz=MzI5MzIwNjA5Nw==&mid=100001237&idx=1&sn=18e513b5acc5491804b65fc70d7f8a52&scene=0#rd

$s = 'http://mp.weixin.qq.com/s?__biz=MzI5MzIwNjA5Nw==&mid=100001237&idx=1&sn=18e513b5acc5491804b65fc70d7f8a52&scene=0#rd';
if(preg_match_all('#http://mp\.weixin\.qq.com/s\?__biz=\w{14}==&mid=\d{9}.+?&sn=\w{32}#i',$s,$m)){
	echo 'OK';
}else{
