利用php实现读取excel中的图片
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

excel图片如下图:

项目实例:
- use PhpOffice\PhpSpreadsheet\Cell\Coordinate;
- use PhpOffice\PhpSpreadsheet\IOFactory;
- $imageFilePath = './uploads/imgs/'; //图片本地存储的路径
- if (!file_exists($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:
