PHP上传问题

Question

我有php上传问题，我有以下代码:

define('GW_UPLOADPATH', '/var/www/train/ch5/images/');
$name = $_POST['name'];
$score = $_POST['score'];
$screenshot = $_FILES['screenshot']['name'];

$target = GW_UPLOADPATH.$screenshot;
echo $_FILES['screenshot']['tmp_name'].'<br/>';
move_uploaded_file($_FILES['screenshot']['tmp_name'], $targe)
or die("Upload Error!");

我收到上传错误!上传文件的临时文件是:

/tmp/php9Khayp

但是在/tmp 中我找不到这个文件。我正在使用 Ubuntu 10.10。谁能告诉我问题出在哪里？

Answer 1

你打错了。 $targe 应该是 $target。

move_uploaded_file($_FILES['screenshot']['tmp_name'], $targe)
                ---------------------------------------^^^^^^

否则，您将永远无法在 /tmp 中看到该文件，因为它只在 PHP 脚本的生命周期内存在。一旦脚本执行完成，文件将被清理。除非成功调用 move_uploaded_file() ，否则在脚本终止后您永远无法在磁盘上访问它。

更新

如果 $target 变量不是问题，请确保 Apache Web 服务器用户(可能是 www-data、httpd、apache)对您的目标 /var 具有写入权限/www/train/ch5/images/:

# assuming the Apache user is apache...
sudo chown root:apache /var/www/train/ch5/images/
sudo chmod g+rwx /var/www/train/ch5/images/
