ThinkPHP's PHPExcel exports multiple image data

I have done an example of data export to Excel in a previous project. I recently needed to export image data. I have never encountered such a project, so when the process is successful, I hereby record it. I hope it can give some inspiration to friends in need!

Back -end controller method:

        /*导入phpExcel核心类 */
        require_once APP_PATH.'PHPExcel/PHPExcel.php';
        require_once APP_PATH.'PHPExcel/PHPExcel/Writer/Excel5.php';     // 用于其他低版本xls
        require_once APP_PATH.'PHPExcel/PHPExcel/Writer/Excel2007.php'; // 用于 excel-2007 格式
 
        //实例化PHPExcel类
        $objPHPExcel = new PHPExcel();
 
        $objPHPExcel->createSheet(0);
        $objPHPExcel->setActiveSheetIndex(0);
        $currentSheet = $objPHPExcel->getActiveSheet();
 
//      $objPHPExcel->getActiveSheet()->getDefaultRowDimension()->setRowHeight(300);#设置单元格行高（此方法经过个人测试，发现会出现excel变形）
 
        // 设置内容居中
        $objPHPExcel->setActiveSheetIndex(0)->getStyle('A')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
        $objPHPExcel->setActiveSheetIndex(0)->getStyle('B')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
        $objPHPExcel->setActiveSheetIndex(0)->getStyle('C')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
        $objPHPExcel->setActiveSheetIndex(0)->getStyle('D')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);

code to share. It needs to be noticed that this time this is the code for the success of my project. You must import the phpExcel core class. This class library file is the key. Free download address: ThinkPHP implements the PHPExcel class library file for exporting data to Excel files. Then it should be noted that when exporting multiple pictures Be sure to remember to instantiate multiple image variables, otherwise variable conflicts and image coverage problems will occur. The last problem is that when reading database data, if the image data does not exist in the database, you need to read the data. Determine whether it is empty, otherwise a program error will occur during operation. If these are paid attention to, then our function will run and present the program well.
