在PHP中创建文件上传目录

Question

我正在创建一个在file_share.php中请求用户名的文件上传表单，然后应该转到允许用户上传文件的上传表单upload.php。

问题在于这句话：

`$full_path = sprintf("/home/dfatoki11/uploading/%s/%s", $username, $filename);`

当我运行该文件时，它说写入会话数据失败，错误被拒绝权限。当设置临时文件来存储上传的文件时，我应该使用哪个目录，以及如何在aws/apache服务器上设置权限？

fileshare.php

<?php
session_start();
  $username = $_SESSION['username'];
  echo $_SESSION['username'];
  ?>

<?php
$myFiles = sprintf("/home/dfatoki11/uploading/%s/%s", $userName, $filename);
$files=scandir($myFiles);

$full_path = sprintf("/home/dfatoki11/uploading/%s/%s", $username, $filename);
$finfo = new finfo(FILEINFO_MIME_TYPE);
$mime = $finfo->file($full_path);

header("content-Type:" .$mime);
readfile($full_path);
?>

<form enctype="multipart/form-data" action="upload.php" method="POST">
<p>
<label for="file">Choose a file to upload:</label> 
<input name="uploadedfile" type="file" id="file" />
<input type="submit" value="Upload File" />
</p>
</form>

upload.php

<?php
        session_start();
        // Get the filename and make sure it is valid
        $filename = basename($_FILES['uploadedfile']['name']);
        if( !preg_match('/^[\w_\.\-]+$/', $filename) ){
           echo "Invalid filename";
           exit();
        } 
        // Get the username and make sure it is valid
        $username = $_SESSION['username'];
        if( !preg_match('/^[\w_\-]+$/', $username) ){
           echo "Invalid username";
           exit();
        } 
        $full_path = sprintf("/home/dfatoki11/uploading/%s/%s", $username, $filename);

              if( move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $full_path) ){
                 header("Location: file_share.php");
                 exit();
              }else{
                 header("Location: login.php");
                 exit();
              }


?>

您可能必须为您的/home文件夹授予用户"www-data“权限。如何做到这一点可以在这里找到：How to give apache permission to write to home directory?
