Ubuntu的新手CATE CANT CATE通过XAMPP上传到网页目录在Windows上工作正常



嗨，我是Linux Ubuntu的新手18.04。我已经安装了XAMPP Web服务器。我的PHP代码在Windows环境上使用XAMPP效果很好。但是，我现在已切换到Linux，当我完成页面以将图像上传到目录时，看来页面已完成处理，但目录本身为空。任何人都可以帮助我尝试过的权限，就像其他论坛和视频所提到的那样，但这没有区别。我是Linux的新手，所以请耐心等待

感谢您的时间

编辑我的代码可能很麻烦，我正在学习php所有数据库调用都可以正常工作。

  • Linux对案例敏感，您是否正确指定了路径以匹配文件系统上的文件夹的情况？
  • 是Webroot中的文件夹 - 如果没有，则可能必须编辑Apache配置才能设置Apache权限以访问该文件夹（不仅仅是文件夹权限）
  • 您是否查看了error.log查看来自PHP的错误输出是什么。Windows通常会打开显示错误，默认情况下，Linux服务器可能不会打开此错误，因此您会缺少错误输出。

简要查看您的代码，尽管不知道其他任何内容，例如文件名，文件夹名称 - 您检查了文件扩展名，但没有降低所有内容（输入扩展和与之比较的数组），以确保在这里确保情况敏感性不是问题。例如，file.jpg和file.jpeg将与您的数组不匹配。

其次，YOUN不检查Move_uploaded_file的结果，这可能有助于确保它在此时成功。如前所述，请检查错误日志。

只是为了补充，此代码充满了安全漏洞 - 可以开始学习，但我不会将其投入到任何地方。
