PHP:move_uploaded_file() 无法打开流:没有那个文件或目录
我正在尝试让 PHP 将上传的文件从 tmp 目录移动到我的网络服务器上的某个永久位置.看起来很简单，但我收到了这个错误:
I'm trying to get PHP to move an uploaded file from the tmp directory to somewhere permanent on my webserver. It seems simple enough, but I'm getting this error:
无法将C:UniServer mpphp3F62.tmp"移动到static/images/slides/1/1.jpg"
很直接，对吧?找不到目标文件夹.
Pretty straight-forward, right? It can't find the destination folder.
我的问题是:如何引用所需的目标目录?
引用是否相对于脚本在服务器上的位置?还是相对于 URL?还是 PHP DOCUMENT_ROOT?还是操作系统的文件系统?或者别的什么?
Is the reference relative to the script's position on the server? Or is it relative to the URL? Or the PHP DOCUMENT_ROOT? Or the OS's filesystem? Or something else?
我在 PHP 文档中或在 SO.. 上的任何类似问题中都找不到答案.
I can't find the answer in the PHP documentation or indeed in any of the similar questions here on SO..
有人可以帮忙吗?谢谢.
Can anyone help? Thanks.
推荐答案
跟踪路径的一个简单方法就是在 index.php 中定义绝对路径
A simple way to keep track of the path is just to define the absolute path in your index.php
define ('SITE_ROOT', realpath(dirname(__FILE__)));
然后像这样使用它:
move_uploaded_file($_FILES['file']['tmp_name'], SITE_ROOT.'/static/images/slides/1/1.jpg');
