Question

I have a script that download’s files from a server, all works nice. But when the file is downloaded either it’s a jpg or png file. I cant seem to open it with any program to view it. (windows photo gallery or fireworks)

When i download a video file (avi). I cant open it with windows media player, but i can open it with vlc media player.

I always get a error msg, cant read file or file broken.

Here is the code, is it reliable or should i consider using fsocketopen or curl maybe.

I have tried altering the headers looking for more answers on the web, with no luck.

Anyone have an idea to whats wrong?

chmod("extensions_img/test.jpg",0755);

$fullPath = "http://www.website_url.com/extensions_img/test.jpg";

if ($fd = fopen ($fullPath, "r")) {

    $fsize = filesize("extensions_img/test.jpg");

    $path_parts = pathinfo($fullPath);
    $ext = strtolower($path_parts["extension"]);

    switch($ext) {

    while(!feof($fd)) {
        $buffer = fread($fd, 4096);
    flush();
    }
}
fclose ($fd);

Answer 1

Try:

while(!feof($fd)) {
    echo fread($fd, 4096);
    flush();
}

You aren’t echoing anything so probably your file is empty?
