Question

我正在使用PHPExcel来解析我的excel文件。我的文件在每一行都有图像。我使用“getDrawingCollection”函数来获取excel文件中的所有图像。它整体工作得很好。但是getDrawingCollection函数无法识别某些图像。我需要更改代码中的任何内容吗？

 $objReader = PHPExcel_IOFactory::createReader('Excel2007');
$objPHPExcel = $objReader->load($uploadfile);

$objWorksheet = $objPHPExcel->getActiveSheet();

    foreach ($objWorksheet->getDrawingCollection() as $drawing) {
        $string = $drawing->getCoordinates();
        $coordinate = PHPExcel_Cell::coordinateFromString($string);


        if ($drawing instanceof PHPExcel_Worksheet_Drawing) {
                          //copy image
       }
    }

Answer 1

if ($drawing instanceof PHPExcel_Worksheet_Drawing) {

不会拿起“记忆图纸”

您可能想要使用

if ($drawing instanceof PHPExcel_Worksheet_BaseDrawing) {

代替;类似的东西：

foreach ($objPHPExcel->getActiveSheet()->getDrawingCollection() as $drawing) {
    if ($drawing instanceof PHPExcel_Worksheet_MemoryDrawing) {
        ob_start();
        call_user_func(
            $drawing->getRenderingFunction(),
            $drawing->getImageResource()
        );

        $imageContents = ob_get_contents();
        ob_end_clean();
        $extension = 'png';
    } else {
        $zipReader = fopen($drawing->getPath(),'r');
        $imageContents = '';

        while (!feof($zipReader)) {
            $imageContents .= fread($zipReader,1024);
        }
        fclose($zipReader);
        $extension = $drawing->getExtension();
    }
    $myFileName = '00_Image_'.++$i.'.'.$extension;
    file_put_contents($myFileName,$imageContents);
}

phpexcel getDrawingCollection - 无法识别某些图像
