非常感谢和问候如果您知道正在将图像的正确路径传递给unlink命令，则运行PHP的用户帐户可能没有对该文件的写入权限
您可能希望在E_警告级别启用错误，然后运行测试脚本以查看是否收到警告。您还应该测试unlink的返回值，因为它在失败时返回FALSE。Hi，感谢您花时间回复。我的问题是，我没有收到任何错误消息，这可能表明是代码而不是权限问题导致的。但是因为我对PHP有点陌生，我不确定我的代码是否有问题。我真的很想确认一下，虽然我很感激这可能只是一种夸张，但我的代码是否正确？Kind Regards此行的语法错误，您缺少一个点来连接最后两个字符串：$file='UploadedFiles/'$_会话['username']./'$_会话['locationid']./''$原名'；vs$file='UploadedFiles/'$_会话['username']./'$_会话['locationid']./'$原名'；看到区别了吗？嗨，格雷格，非常感谢。我明白你的意思。我会做出改变的。关于篮球，我忘了一部分。使用单引号时，不会对变量进行插值。您应该从$originalname中提取单引号，因为它将其视为字符串文字，而不是变量的值。
$galleryPath = 'UploadedFiles/' . $_SESSION['username'] . '/' . $_SESSION['locationid'] . '/';
