坛子里有没有正则高人？求助啊
求个PHP正则验证URL的帖子我的网站文章中有些链接作了xxx，有的没有，我想用正则将全站没有加、标签的http开头的链接都加上链接应该怎么写正则呢？
对于下面这样的内容不作改动[*]http://xxx.xxx.com/xxx/xxx.xxx复制代码[*]
复制代码这样的http开头的内容加标签[*]http://xxx.xxx.com/xxx/xxx.xxx复制代码给个字符串吧[*]

[ 本帖最后由 gdtv 于 2010-10-11 14:40 编辑 ] PHP Example: Automatically link URL's inside text.
$text = preg_replace('@(https?://([-\w\.]+)+(:\d+)?(/([\w/_\.]*(\?\S+)?)?)?)@', '$1', $text); 谢谢高人
但是如果还能在完美点就好了，现在对于下面这种情况会出问题

这个没有考虑已经在img和a标签内情况 [*]$str = preg_replace_callback("/]*href=['"]*http:\/\/[^]*>[^]*/i","remove_http",$str);复制代码这样好像就OK 了 5楼的方法应该算一个变通的方法
先替换标签内URL的http://
在匹配替换http://的URL
再将第一步被替换的还原
不知道还有没有更好的方法，用(?!exp)这类？求正则帝，求一行正则代码实现的方法
