copy（）函数的第二个参数不能是目录

Anyone know why this:

<?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/');
}

Gives:

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

It's because you're moving a file and it thinks you're trying to rename that file to the second parameter (in this case a director).

it should be:

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

You are specifying to move a file to a directory; neither PHP's move_uploaded_file nor its copy is as smart as a shell's copy -- you have to specify a filename, not a directory, for the destination.

So, one simple solution would be to take the basename of the source file and append that to the destination directory.

It sounds like the second argument to move_uploaded_file should be a full file name instead of just the directory name. Also, probably only a style issue, but you should use consistent slashes in 'c:\wamp\www\uploads\images/'

Because PHP is not a shell. You're trying to copy the file into the c:\wamp\www\uploads\images directory, but PHP doesn't know you mean that when you execute (within the move_uploaded_file function):

copy($_FILES['userfile']['tmp_name'], 'c:\wamp\www\uploads\images/');

This command tells it to rename the file to c:\wamp\www\uploads\images/, which it can't do because that's the name of an existing directory.

Instead, do this:

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

if you want just copy the file in two Dir different, try this :

if (move_uploaded_file($_FILES['photo']['tmp_name'], $target.$pic1))
{
  copy("C:/Program Files (x86)/EasyPHP-5.3.9/www/.../images/".$pic1, "C:/Program Files (x86)/EasyPHP-5.3.9/www/.../images/thumbs/".$pic1)
}

You should write the complete path "C:/..."

Try adding the extension to the name file.

$filename = $_FILES['userfile']['tmp_name'].".jpg";

It will be like below in phalcon 3.42

if ($this->request->hasFiles() == true) {
        // Print the real file names and sizes
        foreach ($this->request->getUploadedFiles() as $file) {

            //Print file details
            echo $file->getName(), " ", $file->getSize(), "
";

            //Move the file into the application
            $file->moveTo($this->config->application->uploadsDir.$file->getName());
        }
    }
