PHP bot分配上传路径

Question

我遇到的问题是我的文件上传路径没有分配到正确的文件夹。 它实际上修改了文件路径到正在上载的文件的文件名。 奇怪吧？ 这是我正在处理的代码......

<?php
      $allowed_filetypes = array('.mp4','.gif','.bmp','.png','.html','.psd','.zip','.xml','.css','.js',);
      $max_filesize = 5904288;
      $upload_path = 'video';

   $filename = $_FILES['userfile']['name'];
   $ext = substr($filename, strpos($filename,'.'), strlen($filename)-1);

   if(!in_array($ext,$allowed_filetypes))
      die('Sorry, cannot take files over blankKB.');

   if(filesize($_FILES['userfile']['tmp_name']) > $max_filesize)
      die('Sorry, cannot take files over blankKB.');

   if(!is_writable($upload_path))
     die('We are very sorry, a problem is occurring with the CHMOD  of this directory');

   if(move_uploaded_file($_FILES['userfile']['tmp_name'],$upload_path . $filename))
         echo ' Your file was uploaded successfully, view it <a href="file.php?file=' . $filename . '" target="_blank" title="Your File">here</a>';
      else
         echo 'Sorry, but there was an error during the file upload. Please try again.';
?> 

这是上传后文件的样子，

videoHello.png

加上它不会将文件上传到我想要的目录，位于/ video

Answer 1

当你写$upload_path . $filename $upload_path . $filename你只是连接两个字符串，这确实导致videoHello.png ;

您应该连接系统的目录分隔符（在基于Unix的系统上它是/ ）

$upload_path . '/' . $filename

或者将分隔符构建到字符串$upload_path

$upload_path = 'video/';

虽然我最后的建议是使用像这样的绝对路径：

$upload_path = dirname(__FILE__) . '/video/';
