如何在Laravel中过滤子数组的数组？

Question

如何通过子数组值筛选数组？在这个例子中，我有下面的API请求数组，并且希望只构建一个id为2的新数组，该数组具有name=Other name，因为我的过滤器被设置为Other name

[
  {
    "id": 1,
    "attendees": [
      {
        "emailAddress": {
          "name": "Some Name",
          "address": "mail@some"
        }
      }
    ]
  },
  {
    "id": 2,
    "attendees": [
      {
        "emailAddress": {
          "name": "Other Name",
          "address": "mail@other"
        }
      }
    ]
  }
]

是否有方法执行foreach并填充新数组if(name==selected name)？

相反，forach可以考虑Laravel集合，将数组转换为集合，然后使用filter方法。示例：

    $collection = collect([
        [
            "id" => 1,
            "attendees"=> [
            [
                "emailAddress" => [
                "name"=> "Some Name",
                "address"=> "mail@some"
                ]
            ]
            ]
        ],
        [
            "id" => 2,
            "attendees" => [
                [
                    "emailAddress"=> [
                    "name"=> "Other Name",
                    "address"=> "mail@other"
                    ]
                ]
            ]
        ]
    ]);

    $filter = "Other Name";
    $filtered = $collection->filter( function( $value, $key ) use ( $filter ) {
        $attendees = collect( $value[ "attendees" ] );
        
        $filteredAttendees = $attendees->filter( function( $value, $key ) use ( $filter ){
            return $value["emailAddress"]["name"] === $filter;
        } );
        
        return count( $filteredAttendees ) > 0;
    });

    dd( $filtered->toArray( ));

foreach ( $array as $k=>$v )
{
    if($array[$k]['id']==2 && $array[$k]['name'] == selected name){
         //make new array here...
    }
}
