小弟初学PHP，望高人指点。我的这个正则表达式为什么在 php 中通不过呢；在 .net  下是可以通过的
我现在主要想要得到 http://shop.ebay.com/merchant/aboutsales 页中的所有 Url 连接
望高人指点下

Answer 1

帮帮忙了 
写的正则在工具里都能匹配 
就是放到php方法里就不行了 
不晓得是怎么回事

Answer 2

preg_match_all( '/(?:(?:http:\/\/)?\w+\.)(\w+\.\w+(?:\.\w+)?)/ ',$gethtml,$array);

Answer 5

去掉preg_match_all( '/(?:(?:http:\/\/)?\w+\.)(\w+\.\w+(?:\.\w+)?)/ ',$gethtml,$array);红问号才是所有连接吧
不知道2楼为什么加这个问号。要不匹配的可以是任何\w.\w.\w啊。会有差异吧。希望2楼给讲讲。呵呵。本人小菜

Answer 6

?匹配前面的子表达式零次或一次去掉的话，就有可能 匹配不了 没有 http:// 的条件了

Answer 7

我知道？的用法，但是要是这么写。里面的废信息太多了。任何\w.\w.\w东西都会出来，而且会漏掉https
我也写了个。只供参考。2楼看看要是不合理。提出改正。呵呵。preg_match_all('/href=\"([^\"]+?[\/\.]+[^\"]+?)\"/',$gethtml,$array);
foreach ($array[1] as $u)
{ 
    $url = $u; 
    echo trim($url)."<br />";
}
