PHP中excel带图片数据导入

前提：有个需求需要实现带图片的excel数据导入数据库中，发现PHPExcel - Excel 操作库已经停止维护，在PHP8的版本中，有些语法不支持，报错一堆，改了一堆，又还有一堆。所以决定找个替代的扩展：phpoffice/phpspreadsheet

技术背景前提：

ThinkPHP8.0
php8.0.2nts
“phpoffice/phpspreadsheet”: “^1.20.0”

在composer.json中加入"phpoffice/phpspreadsheet": "^1.20.0"后composer update，如果选择的phpoffice/phpspreadsheet版本不同，可能又有不同的坑存在，得进行一一排查。这里记录下。

实现步骤看代码注释部分，实现代码如下：

    /*** 字母序列化为数字*/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 $ten;}public function excel(){if ($file = request()->file('excel')) {try {$saveName = Filesystem::disk('public')->putFile('/static/upload/excels', $file);if (!is_file($saveName)) {return json(['code' => 1, 'msg' => '文件不存在', 'data' => null]);}$ext = pathinfo($saveName, PATHINFO_EXTENSION);// xls不支持图片导入// if (!in_array($ext, ['xlsx', 'xls'])) {if (!in_array($ext, ['xlsx'])) {return json(['code' => 1, 'msg' => '文件类型不正确', 'data' => null]);}// 有两种格式，xlsx和xlsif ($ext == 'xlsx') {$objReader = IOFactory::createReader('Xlsx');} else {$objReader = IOFactory::createReader('Xls');}// 图片保存路径$imageFilePath1 = root_path() .
