什么样的正则表达式可以将value的值得到?

求前辈指导,不胜感激。


回复讨论(解决方案)

preg_match('/value="(.+?)"/','',$m);
echo $m[1];

preg_match('/value="(.+?)"/','',$m);
echo $m[1];
我问的问题不对..嘿嘿  
比如说有这么多









从这么多里面匹配到里面的value值

$s=<<<txt<input type="hidden" name="tpl" value=""/><input type="hidden" name="tn" value=""/><input type="hidden" name="pu" value=""/><input type="hidden" name="ssid" value=""/><input type="hidden" name="from" value=""/><input type="hidden" name="bd_page_type" value=""/><input type="hidden" name="uid" value="1368705235817_885"/><input type="hidden" name="type" value=""/><input type="hidden" name="regtype" value=""/>txt;preg_match('/name="uid" value="(.+?)"/',$s,$m);echo $m[1];
