今天文件上传出现Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move

<form action="" enctype="multipart/form-data" method="post">
<tr>
  <td width="150" height="30" align="right" valign="middle">请选择上传文件</td>
  <td width="250"><input type="file" name="fileup" /></td>
  <td width="100"><input type="submit" name="submit" value="上传" /></td>
</tr>
</form>
<?php教程
if(!empty($_FILES[fileup][name])){
    $fileinfo=$_FILES[fileup];
        $type=strstr($fileinfo['name'],".");
        if($type!=".jpg"){
          echo "您上传的文件格式不正确！";
        }else{
          if($fileinfo['size']<209715 && $fileinfo['size']>0){
             $path="10/".$_FILES["fileup"]["name"];
                 move_uploaded_file($fileinfo['tmp_name'],$path);
                 if(is_dir("10/")){
                   $dir=scandir("10/");
                   foreach($dir as $value){
                     echo $value."<br/>";
                   }
                 }else{
                    echo "目录路径出错！";
                 }
          }else{
          echo '文件大小不符合要求！';
          }
        }
}
?>

运行结果：
Warning: move_uploaded_file(10/02.jpg) [function.move-uploaded-file]: failed to open stream: No such file or directory in E:apps教程erv-win32-2.5.10AppServwww10index_7.php on line 26

Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move 'C:WINDOWStempphp1A.tmp' to '10/02.jpg' in E:appserv-win32-2.5.10AppServwww10index_7.php on line 26
目录路径出错！

解决办法,把相对路径改绝对

$_SERVER[DOCUMENT_ROOT] . '/10/' . $_FILES['fileup']['name'];

解决办法
将
move_uploaded_file($_FILES["file"]["tmp_name"],"upload/" . $_FILES["file"]["name"])
改为
move_uploaded_file($_FILES["file"]["tmp_name"],"d:/" . $_FILES["file"]["name"])

方法二

Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move
上传的时候出现类似这种报错，原因是目录权限是否为可写的问题。
一般设置777就可以解决。、
修改权限命令：

chmod 777 filename
chmod 777 dirname
sudo chmod 777 filename/dirname
chown wangr:admin dirname -R

注：-R 批量执行
