使用maatwebsite将多维数组导出为CSV和JSON

Question

我有一个关于导出数据的问题。

我正在使用带有laravel 5.4的maatwebsite。我有一个像这样的数组：

array:8 [▼
  "company_id" => "2"
  "company_name" => "Test Company2"
  "survey_id" => "1"
  "survey_name" => "ELMAO"
  "customer_id" => "5"
  "customer_first_name" => "Lol"
  "customer_last_name" => "Kek"
  "questions" => array:2 [▼
    0 => array:4 [▼
      "question_name" => "1"
      "question_title" => ""
      "response_text" => "2"
      "screenshot_url" => "iVBORw0KGgoAAAANSUhEUgAAAeAAAAHvCAYAAACMggxAAAAgAElEQVR4XuydCZwdVZX/f/W2XpLOvq9kYwkh7BACjKCCrAEMmywqiqij4gAqOjoqo6OOOgoDKjgqyoCIiIp/GEH2fcdAyB5IyL4nvfdb6//5nXqv ▶"
    ]
    1 => array:4 [▼
      "question_name" => "7"
      "question_title" => "Keek!"
      "response_text" => "2"
      "screenshot_url" => "iVBORw0KGgoAAAANSUhEUgAAAeAAAAHvCAYAAACMggxAAAAgAElEQVR4XuydB7hcZbX+3z3tlPRGeg+EQAhBSkKAK6ggUkIJTYqKIupV8Qooer1XRb3qVa/CRRFsKBdERFT8g4D03iEQ0kggIb2enH6mz/95156J ▶"
    ]
  ]
]

如何将此数据导出到CSV文件以及作为JSON字符串？

从eloquent模型中检索数据时，您已构建函数以将其设置为JSON。 https://laravel.com/docs/5.5/eloquent-serialization#serializing-to-arrays
