将相似的元素合并成一个多维 PHP 数组
Merge similar elements into a multi-dimensional PHP array
所以我有一个具有相似元素的数组，我需要将它合并到一个多维数组中，将一些元素合并在一起，我可能对生活要求太多，但我想我会问。 .. 提前致谢:)
我当前的数组：
Array
(
[0] => Array
(
[name] => Facebook
[icon] =>
[sectors] => BSS
[url] => http://www.facebook.com/...

我会这样做：
foreach ($original_array as $value){
$result_array[$value['name']]['name'] = $value['name'];
$result_array[$value['name']]['icon'] = $value['icon'];
$result_array[$value['name']]['sectors'][] = array(
'name' => $value['sectors'],
'url' => $value['url']
}
我正在做的是使用名称（Facebook、Youtube 等）作为数组键，以便能够推送（使用 []）子数组的扇区和 url 元素进入他们自己的子阵列。
从这里您可以按原样 return $result_array 或者如果您确实需要索引数组，return array_values($result_array)
我假设图标不会在具有相同名称的两个条目之间改变。如果不是这种情况，您可以对名称 + 图标进行散列，或者只是连接名称和图标并将其用作数组键。
