curl or wget gets invalid jpg image but browser gets valid image

Question

I run command like

wget https://odis.homeaway.com/odis/listing/5895882c-6c65-47f5-b782-e13b8246e4aa.c10.jpg

I try to get above image using curl, the returned image is invalid jpg image. When I try with browser and save image as, I get valid jpg image. Even when I try with file_get_contents it returns false.

    $image = 'https://odis.homeaway.com/odis/listing/5895882c-6c65-47f5-b782-e13b8246e4aa.c10.jpg'
    $image_data = file_get_contents($image);
    try {
        echo 'saving';
        $image1 = imagecreatefromjpeg($image_data);

    } catch (Exception $ex) {
        echo 'error';
    }

How to get this image with curl, wget, or file_get_contents?

it's a bug with the odis.homeaway.com server, you should send their webmaster a bugreport.

their server ALWAYS send the image in https://odis.homeaway.com/odis/listing/5895882c-6c65-47f5-b782-e13b8246e4aa.c10.jpg gzip compressed, even if the client did NOT specify accept-encoding: gzip. wget doesn't support gzip compression at all, but curl does. until they fix their server, you can tell curl to decompress it for you automatically by setting the --compressed argument in the command line version, or setting CURLOPT_ENCODING=>'gzip' in the curl_ api, or running it through gzdecode(), eg $image_data = gzdecode(file_get_contents($image)); (the gzdecode() method is NOT recommended, because this will stop working once they actually fix their server, and only works now because their server is bugged). the reason your browser isn't affected by the bug, is that all mainstream browser always sends Accept-Encoding: gzip (and others) by default.

edit: originally i mentioned gzuncompress(), not gzdecode(), that was a mistake, the correct decompression function is gzdecode().
