php中的组数组

Question

我有一个数组，其中包含如下数据：

Array    (
[0] => Array (
        [www.google.com] => www.google.com/a
    )
[1] => Array (
        [www.google.com] => www.google.com/a
    )
[2] => Array (
        [www.test.com] => www.test.com
    )
[5] => Array (
        [www.test.com] => www.test.com/c
    )
)

我需要像这样对特定网址的所有链接进行格式化：

Array (
 [www.google.com] => Array (
      [0] => www.google.com/a
      [1] => www.google.com/a
      )
 [www.test.com] => Array (
      [0] => www.test.com
      [1] => www.test.com/c
      )
  )

请为此提供帮助吗？

Answer 1

如果我们调用第一个数组$domains。

$groups = array();

for ($i = 0; $i <= count($domains); $i++)
{
    foreach ($domains[$i] as $domain => $url)
    {
         $groups[$domain][] = $url;
    }
}

print_r($groups);

那可能有用......
