我不会将xlsx文件导入到我的mysql数据库中。为此，我使用了nuovo电子表格阅读器库： https://github.com/nuovo/spreadsheet-reader/ 我可以在此站点中将简单的xlsx文件导入数据库： https://phppot.com/php/import-excel-file-into-mysql-database-using-php/
但是当我修改要导入播放器的文件时，上传完成，但是数据库中没有任何内容。我不明白为什么。
用于读取和注入数据库中数据的代码：

我有响应“文件已上载”，但没有数据库中的数据。
答案 0 :(得分：0)
最后我改变了图书馆，因为我不能使用数字。我改为PHPOFFICE。现在一切正常。我的代码不是最好的，仅适用于开发人员，但它可以工作：
