php判断上传的Excel文件中是否有图片及PHPExcel库认识

需要借助PHPExcel这个库
代码如下:
$excelPath = 'Test.xls';

$objReader = PHPExcel_IOFactory::createReader('Excel5');
$objReader->setReadDataOnly(true);

$objPHPExcel = $objReader->load($excelPath);
$currentSheet = $objPHPExcel->getActiveSheet();
$AllImages= $currentSheet->getDrawingCollection();

if(count($AllImages) > 0) {
//处理
}
