Php 脚本无法打开流

我正在尝试设置上载站点，但无法获取上载文件的脚本。（上载文件夹的所有权限均设置为777。）我继续收到以下错误：

Warning: move_uploaded_file(/var/chroot/home/content/44/9976344/html/tech/filemanager/uploads/Ace_planning_instructions.docx) [function.move-uploaded-file]: failed to open stream: No such file or directory in /home/content/44/9976344/html/tech/tech/js/upload.php on line 72

Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move '/tmp/phpo89pGR' to '/var/chroot/home/content/44/9976344/html/tech/filemanager/uploads/Ace_planning_instructions.docx' in /home/content/44/9976344/html/tech/tech/js/upload.php on line 72
Error! Most likely upload directory doesn't have writable permissions or you didn't set it up correctly. 

我可以做些什么来修复或解决这些错误

据我所知，您正在将上载复制到错误的目录
“/var/chroot/home/content/44/9976344/html/tech/filemanager/uploads/”和“/home/content/44/9976344/html/tech/filemanager/uploads/”如果其中一个是最有可能的符号链接，则它们不相同。使用路径“/home/content/44/9976344/html/tech/filemanager/uploads/”而不是您之前使用的路径“/var/chroot/home/content/44/9976344/html/tech/filemanager/uploads/”。仅包含有关其链接到的文件的信息
 你明白例外情况吗
没有这样的文件或目录
听起来像是在错误的位置查找文件。您可以使用
是否可读（$filePath）
检查文件路径是否有效（并且可读）。您可以发布与此一起使用的表单吗？或者如果不是，这篇文章是否使用了多部分/表单数据编码？我确实理解这个例外。我运行install.php脚本并在主机中创建目录，所有目录都具有777访问权限。我想从我的桌面上传一个文件Alex，你这是什么意思？？我使用的程序是Advanced File Manager有人能更好地解释如何修改上面的upload.php代码以使其正常工作吗>
