php - 菜鸟不能用php上传txt文件

Question

我正在使用以下 php 文件，

结果

Upload: test.com.html
Type: text/html
Size: 135.921875 kB
Stored in: /tmp/phpA8DGdB
Possible file upload attack! 

Here is some more debugging info:
    Array ( 
          [file] => 
             Array ( 
                    [name] => test.com.html
                    [type] => text/html 
                    [tmp_name] => /tmp/phpA8DGdB 
                    [error] => 0
                    [size] => 139184 
         ) 

    )

PHP 文件：-

 <?php
 if ($_FILES["file"]["error"] > 0)
 {
  echo "Error: " . $_FILES["file"]["error"] . "<br>";
 }
 else
 {
   echo "Upload: " . $_FILES["file"]["name"] . "<br>";
   echo "Type: " . $_FILES["file"]["type"] . "<br>";
   echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
   echo "Stored in: " . $_FILES["file"]["tmp_name"];
 }
 $uploaddir = '/var/www/setup/upload';
 $uploadfile = $uploaddir . basename($_FILES['file']['name']);

 echo '<pre>';
 if (move_uploaded_file($_FILES['file']['tmp_name'], $uploadfile)) {
 echo "File is valid, and was successfully uploaded.\n";
 } else {
 echo "Possible file upload attack!\n";
 }
 echo 'Here is some more debugging info:';
 print_r($_FILES);
 print "</pre>";
 ?> 

所以，我无法上传文件。我会很感激任何提示，在此先感谢:-)

您需要在$uploaddir和文件名之间使用目录分隔符：

$uploaddir = '/var/www/setup/upload/';
$uploadfile = $uploaddir . basename($_FILES['file']['name']);
