要实现读取excel中的图片，可以通过phpspreadsheet来实现。phpspreadsheet是一个纯php编写的库，并引入了命名空间、PSR规范等。
使用composer安装phpspreadsheet
composer require phpoffice/phpspreadsheet
GitHub下载：

excel图片如下图：
项目实例：
use PhpOfficePhpSpreadsheetCellCoordinate;
use PhpOfficePhpSpreadsheetIOFactory;
$imageFilePath = './uploads/imgs/'; //图片本地存储的路径
if (!file_exists($imageFilePath)) { //如果目录不存在则递归创建
mkdir($imageFilePath, 0777, true);
}
try {
$inputFileName = './files/1.xlsx'; //包含图片的Excel文件
$objRead = IOFactory::createReader('Xlsx');
$objSpreadsheet = $objRead->load($inputFileName);
$objWorksheet = $objSpreadsheet->getSheet(0);
$data = $objWorksheet->toArray();
foreach ($objWorksheet->getDrawingCollection() as $drawing) {
list($startColumn, $startRow) = Coordinate::coordinateFromString($drawing->getCoordinates());
$imageFileName = $drawing->getCoordinates() . mt_rand(1000, 9999);
switch ($drawing->getExtension()) {
case 'jpg':
case 'jpeg':
$imageFileName .= '.jpg';
$source = imagecreatefromjpeg($drawing->getPath());
imagejpeg($source, $imageFilePath . $imageFileName);
break;
case 'gif':
$imageFileName .= '.gif';
$source = imagecreatefromgif($drawing->getPath());
imagegif($source, $imageFilePath . $imageFileName);
break;
case 'png':
$imageFileName .= '.png';
$source = imagecreatefrompng($drawing->getPath());
imagepng($source, $imageFilePath, $imageFileName);
break;
}
$startColumn = ABC2decimal($startColumn);
$data[$startRow-1][$startColumn] = $imageFilePath . $imageFileName;
}
dump($data);die();
} catch (Exception $e) {
throw $e;
}
public function ABC2decimal($abc)
{
$ten = 0;
$len = strlen($abc);
for($i=1;$i<=$len;$i++){
$char = substr($abc,0-$i,1);//反向获取单个字符
$int = ord($char);
$ten += ($int-65)*pow(26,$i-1);
}
return $ten;
}结果如图：

$objReader = PHPExcel_IOFactory::createReader('Excel5');
// 设置载入含有贴图的 sheet
$objReader->setLoadSheetsOnly(array('sheet1'));
$objPHPExcel = $objReader->load('test.xls');
$drawing = new PHPExcel_Writer_Excel2007_Drawing();
$drawingHashTable = new PHPExcel_HashTable();
$drawingHashTable->addFromSource($drawing->allDrawings($objPHPExcel));
for ($i = 0; $i < $drawingHashTable->count(); ++$i)
{
$memoryDrawing = $drawingHashTable->getByIndex($i);
if ($memoryDrawing instanceof PHPExcel_Worksheet_MemoryDrawing)
{
$filename = 'images/' . $memoryDrawing->getCoordinates() . '_' . $memoryDrawing->getHashCode() . '.jpg';
// 将图片存到指定的目录
imagejpeg($memoryDrawing->getImageResource(), $filename);
// 获得该图片所在的单元格
$cell = $memoryDrawing->getWorksheet()->getCell($memoryDrawing->getCoordinates());
// 将该单元格的值设置为单元格的文本加上图片的 img 标签
$cell->setValue($cell->getValue() . '<img src="' . $filename . '" />');
}
}
// 再处理将这些单元格的值存入数据库
// ... ...
