PHP警告：move_uploaded_file（）无法移动 [英] PHP Warning: move_uploaded_file() unable to move

问题描述

我一直在慢慢学习PHP，并发现了一系列关于其他开发者发布的主题和解决方案的信息。我试图让一个Android应用程序通过HTTP post将文件上传到PHP服务器。但是，我的服务器端尝试在PHP中写入文件时无法正常工作。

这是PHP代码：

  //文件在哪里将被放置
 $ target_path =/ var / www / media2net / uploads / uploads; 
 
 / *将原始文件名添加到我们的目标路径。 
结果是uploads / filename.extension* / 
 $ target_path = $ target_path。基名（$ _ FILES [ UploadedFile的] [名称]）; 
 
 if（move_uploaded_file（$ _ FILES ['uploadfile'] ['tmp_name']，$ target_path））{
 echo该文件。 basename（$ _FILES ['uploadedfile'] ['name']）。 
已上传; 
 chmod（uploads /。basename（$ _ FILES ['uploadedfile'] ['name']），755）; 
} else {
 echo上传文件时出错，请再试一次！ 
 echofilename：。 basename（$ _FILES ['uploadedfile'] ['name']）; 
 echotarget_path：。$ target_path; 
} 
  

我已经从客户端检查线鲨知道http发送了正确地，我也确保我正在写文件的目录具有正确的权限，并且php安全模式被设置为关闭。

apache2 error.log文件的输出读取

  [Wed Dec 05 09:25:36 2012] [error] [client 74.14.162.250] PHP警告：
 move_uploaded_file（）：无法将'/ tmp / phpVLOnn3'移动到
'/ var / www / media2net /uploads/downloaded_file.png'
在/var/www/media2net/upload.php第9行
  

任何帮助这个问题或进一步的方法来解决这个问题将不胜感激。

解决方案

更改/ var / www / media2net / uploads /通过更改所有者chown或chmod

示例

  $ sudo chown apache：apache / var / www / media2net / uploads / 
 $ sudo chmod 755 / var / www / media2net / uploads / 
  

另外，如果 downloaded_file.png 已经存在于该目录中，另一个用户，那么您也需要更改该文件的所有权。

  $ sudo chown apache：apache /var/www/media2net/uploads/downloaded_file.png 
  

这样，它可以被Apache成功覆盖。

I've been slowly learning PHP and have found an array of information on the subject and solutions posted by other developers. I am attempting to have an android application upload a file to PHP server via HTTP post. However something is not working on my server side wile attempting to write to file in PHP.

Here is the PHP code:

// Where the file is going to be placed
$target_path = "/var/www/media2net/uploads/uploads";

/* Add the original filename to our target path.
Result is "uploads/filename.extension" */
$target_path = $target_path . basename($_FILES['uploadedfile']['name']);

if (move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
    echo "The file ".  basename( $_FILES['uploadedfile']['name']) .
        " has been uploaded";
    chmod("uploads/" . basename($_FILES['uploadedfile']['name']), 755);
} else {
    echo "There was an error uploading the file, please try again!";
    echo "filename: " . basename( $_FILES['uploadedfile']['name']);
    echo " target_path: " .$target_path;
}

I already know from inspecting wire shark on client side that http post is sent out correctly, also I have ensured that the directory I'm writing the file to has the correct permissions, and php safe mode is set to off.

the output from apache2 error.log file reads

[Wed Dec 05 09:25:36 2012] [error] [client 74.14.162.250] PHP Warning:  
move_uploaded_file(): Unable to move '/tmp/phpVLOnn3' to  
'/var/www/media2net/uploads/downloaded_file.png' 
in /var/www/media2net/upload.php on line 9

Any help with this problem or further ways to trouble shoot this would be appreciated.

解决方案

Change upload permissions for /var/www/media2net/uploads/ either by changing owner with "chown" or by "chmod"

Examples

$ sudo chown apache:apache /var/www/media2net/uploads/
$ sudo chmod 755 /var/www/media2net/uploads/

Also, if downloaded_file.png already exists in that directory and it's owned by another user, then you would need to change ownership on that file as well.

$ sudo chown apache:apache /var/www/media2net/uploads/downloaded_file.png

This way, it can be successfully overwritten by Apache.
