Hyperf用csv導出excel表格

use PhpOffice\PhpSpreadsheet\IOFactory;
use PhpOffice\PhpSpreadsheet\Spreadsheet;

 

控制器：

public function index()
    {
        $head = ['name'=>'名字','score'=>'得分'];
        $data = [
            ['name' => '張三', 'score' => '80'],
            ['name' => '李四', 'score' => '90'],
            ['name' => '王五', 'score' => '60'],
        ];

        return TestLogic::export($head,$data,'測試.csv');
    }

 

邏輯層：

 public static function export(array $head,array $body,string $file_name)

  {
        $head_keys = array_keys($head);
        $head_values = array_values($head);
        $fileData = self::utfToGbk(implode(',',$head_values)) . "\n";

        if(strpos($file_name,'.') === false){
            $file_name .= '.csv';
        }

        foreach ($body as $value) {
            $temp_arr = [];
            foreach($head_keys as $key){
                $temp_arr[] = $value[$key] ?? '';
            }
            $fileData .= self::utfToGbk(implode(',',$temp_arr)) . "\n";
        }

        $response = new Response();
        $content_type = 'text/csv';
        return $response->withHeader('content-description', 'File Transfer')
            ->withHeader('content-type', $content_type)
            ->withHeader('content-disposition', "attachment; filename={$file_name}")
            ->withHeader('content-transfer-encoding', 'binary')
            ->withHeader('pragma', 'public')
            ->withBody(new SwooleStream($fileData));
    }

    /**
     * 字符轉換（utf-8 => GBK）
     * @param $data
     * @return false|string
     */
　　　　
   public static function utfToGbk($data)
   {
      return mb_convert_encoding($data,"GBK","UTF-8");
   }
