php copy() using destination absolute path

Question

I cannot google anywhere that one cannot use absolute path in copy() destination. However,

$baseUrl_master_MM = "http://mysite.öä/MM/";
$img_dir = 'img_1';
$img = '01.jpg';

$orig_online = $baseUrl_master_MM.$img_dir.'/'.$img;
$dest_online = '../../mm_img/'.$img_dir.'-online.jpg';
$copy = copy($orig_preview, $dest_preview);

works fine, but the same with absolute path

$baseUrl_master_MM = "http://mysite.öä/MM/";
$baseUrl_master_MM_online = "http://mysite.öä/mm_img/";
$img_dir = 'img_1';
$img = '01.jpg';

$orig_online = $baseUrl_master_MM.$img_dir.'/'.$img;
$dest_online = $baseUrl_master_MM_online.$img_dir.'-online.jpg';
$copy = copy($orig_preview, $dest_preview);

will give no errors and copies no files.

Destination directory exists, and rights are 777. Am I missing something?

Yes, you're missing something. When the source is an URL, PHP is smart enough to download it for you (it actually uses HTTP for this - it has no idea that it's your website/the current website) and then when you try to use it in the destination, it obviously gives up as it can't just upload to a website. Just use an absolute *server* path (`eg. /home/user/www/mm_img/` or `C:\wamp\www\mm_img\ `). `dirname(__FILE__)` will give you the directory of the current file. An absolute path is not the same as an absolute URL. — h2ooooooo, Jun 03 '14 at 11:54
What you're using is not the server's absolute path, it's the public web address.If you really want the absolute path see this question: http://stackoverflow.com/questions/4645082/get-absolute-path-of-current-script — Arthur Silva, Jun 03 '14 at 11:56

Please do the following :

   if(!@copy($orig_preview, $dest_preview))
    {
        $errors= error_get_last();
        echo "COPY ERROR: ".$errors['type'];
        echo "<br />\n".$errors['message'];
    } else {
        echo "File copied from remote!";
    }

Tell what the error's you see?

Also absolute path should look like :

   $abs =  $_SERVER['PHP_SELF'];

Sorry for post as answer , couldn't post as comment

Yes, it gives: COPY ERROR: 2 copy(httu://www.mysite.öä/mm_img/MM-1167-preview.jpg): failed to open stream: HTTP wrapper does not support writeable connections. After getting less ignorant on absolute and public paths, it gives File copied from remote! Thank you all! – Konservin Jun 03 '14 at 12:10

You can't use the HTTP protocol to copy a file on a server. Taken from the PHP documentation on HTTP wrapper

Allows read-only access to files/resources via HTTP 1.0, using the HTTP GET method.

To copy to your local server, use an absolute path.

You might want to explain to OP what an "absolute path" is, as OP said "*works fine, but the same with absolute path*". – h2ooooooo Jun 03 '14 at 12:03
