为此目的使用php 电子表格

class ExcelImport
{
    /**
     * @var
     */
    protected $excel;
    /**
     * @var
     */
    protected $work_sheet;
    /**
     * @var array
     */
    protected $excel_data = [];
    /**
     * ExcelImport constructor.
     * @param Request $request
     * @throws \PHPExcel_Exception
     * @throws \PHPExcel_Reader_Exception
     */
    public function __construct(Request $request)
    {
        //Load file from request
        $this->excel = PHPExcel_IOFactory::load($request->file('file'));
        //Get active sheet
        $this->work_sheet = $this->excel->getActiveSheet();
    }
    /**
     * @return array
     */
    public function import()
    {
        //Iterate through drawing collection
        foreach ($this->work_sheet->getDrawingCollection() as $drawing) {
            //check if it is instance of drawing
            if ($drawing instanceof PHPExcel_Worksheet_Drawing) {
                //creating image name with extension
                $file_name = str_replace(' ', '_', $drawing->getName()).'.'.$drawing->getExtension();
                //Get image contents from path and store them in Laravel storage
                Storage::put('public/'.$file_name, file_get_contents($drawing->getPath()));
                //create images array initially
                $this->excel_data[] = [
                    'image' => $file_name
                ];
            }
        }
        //Map other data present in work sheet
        return $this->rowData();
    }
    /**
     * @return array
     */
    private function rowData()
    {
        $i = 0;
        //Iterate through row by row
        foreach ($this->work_sheet->getRowIterator(2) as $row) {
            //iterate through cell by cell of row
            foreach ($row->getCellIterator() as $cell) {
                //In case of image data that would be null continue
                //We have already populated them in array
                if(is_null($cell->getValue())){continue;}
                //Map other excel data into the array
                $this->excel_data[$i]['name'] = $cell->getValue();
            }
            $i++;
        }
        //Return final data array
        return $this->excel_data;
    }
}
