解析和排序链接

Question

我想解析和排序一组链接 这是一个例子

表格代码

<form name="frm" method="post" action="test.php">
<textarea id="url" name="url"></textarea>
<input type="Submit" name="Submit" value="Submit"/>
</form>

我将每行提交以下链接

http://www.google.com/moo
http://www.yahoo.com/boo
http://www.google.com/zee
http://www.bing.com/kee
http://www.yahoo.com/foo

这是2 on google和2 on yahoo以及1 on bing链接

test.php代码如下（表单发送提交的地方）

<?PHP
$url=$_POST['url'];
$url=nl2br($url);
$url=explode("<br />",$url);
foreach ($url as $value ){
$encrypt = md5($value);
echo $encrypt . "<br>";
}
?>

输出如下

8ec5ec689ab94e5df9d89cea624e7e5e //google.com/moo
b165a8209254d205a2950f23214125ec //yahoo.com/boo
fc8d853005d21a7fc8abb06aba0756fb //google.com/zee
f691aab0c39f288f503ae61d3cc3b5b4 //bing.com/kee
8f55ee4d5227f87ec1316e0fa6c61e3b //yahoo.com/foo

现在我的问题

我想解析主持人知道google,yahoo and bing上的哪一个并对其进行排序，然后将结果显示如下

google.com // parsed and sorted
fc8d853005d21a7fc8abb06aba0756fb //google.com/zee
8ec5ec689ab94e5df9d89cea624e7e5e //google.com/moo

yahoo.com // parsed and sorted
b165a8209254d205a2950f23214125ec //yahoo.com/boo
8f55ee4d5227f87ec1316e0fa6c61e3b //yahoo.com/foo

bing.com // parsed and sorted
f691aab0c39f288f503ae61d3cc3b5b4 //bing.com/kee

所以在语言中我的意思是我想对主机上的链接进行排序，然后在其解析的主机下显示每个组的结果。

我想我需要做很多foreach !!

任何想法怎么做〜谢谢

代码：

$urlByHost = array();
foreach (explode("\n", $_POST['url']) as $value) {
    $parse = parse_url($value);
    $urlByHost[$parse['host']][] = array(
        'url' => $value,
        'parse' => $parse,
        'md5' => md5($value),
    );
}
asort($urlByHost);

print_r($urlByHost);

输出：

Array

        (
            [0] => Array
                (

我认为您需要所有数据。

Answer 2

您可以通过提取域并将其用作具有加密值的数组的索引来实现，如下所示：

$url=$_POST['url'];
$url=nl2br($url);
$url=explode("<br />",$url);
$urls = array();
foreach ($url as $value ){
   $arr = explode('www.',$value);
   $encrypt = md5($value);
   $urls[$arr[1]][]= $encrypt; //this line now fixed, had an error
}
foreach($urls as $key => &$val) {
   echo $key . "<br>";
   foreach($val as $v) {
      echo $v . "<br>";
   }
   echo "<br>";
}
