应用move_uploaded_file()函数上传时出错，提示路径错误。

代码：
<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
 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：
