php - copy() 函数的第二个参数不能是目录

Question

谁知道这是为什么:

<?PHP
$title = trim($_POST['title']);
$description = trim($_POST['description']);

// Array of allowed image file formats 
$allowedExtensions = array('jpeg', 'jpg', 'jfif', 'png', 'gif', 'bmp');

foreach ($_FILES as $file) {
  if ($file['tmp_name'] > '') {
    if (!in_array(end(explode(".",
            strtolower($file['name']))),
            $allowedExtensions)) {
      echo '<div class="error">Invalid file type.</div>';
    }
  }
}

if (strlen($title) < 3)
  echo '<div class="error">Too short title</div>';
else if (strlen($description) > 70)
  echo '<div class="error">Too long desccription.</div>';

else {
  move_uploaded_file($_FILES['userfile']['tmp_name'], 'c:\wamp\www\uploads\images/');
}

给予:

Warning: move_uploaded_file() [function.move-uploaded-file]: The second argument to copy() function cannot be a directory in C:\wamp\www\upload.php on line 41

Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move 'C:\wamp\tmp\php1AB.tmp' to 'c:\wamp\www\uploads\images/' in C:\wamp\www\upload.php on line 41

Answer 1

这是因为您正在移动文件并且它认为您正在尝试将该文件重命名为第二个参数(在本例中为目录)。

应该是:

move_uploaded_file($_FILES['userfile']['tmp_name'], 'c:/wamp/www/uploads/images/'.$file['name']);
