Answer 1

试试下面的代码：假设您的数据看起来像下面的数组，即$ arrays。

$arrays=[ 
                    ["name" => "Khv","emails" => 
                        [0 => ["email" => "demo1@yahoo.com"]
                        ]
                    ],
                    ["name" => "asy", "emails" => 
                        [0 => ["email" => "demo2@yahoo.com"]
                        ]
                    ]
                ];
        $emails=collect();
        foreach ($arrays as $array) {
            $emails->push($array['emails'][0]['email']);
        }
        dd($emails);

注意：不能在数组上使用pluck，只能在集合上使用。
