Save a copy of the photo from the Google Places API. Post a photo using curl

Question

I am trying to capture a photo from Google Place Photos using curl and save it on my server.

The request format according to the Google API documentation is as follows:

https://maps.googleapis.com/maps/api/place/photo?maxwidth=400&photoreference=CoQBegAAAFg5U0y-iQEtUVMfqw4KpXYe60QwJC-wl59NZlcaxSQZNgAhGrjmUKD2NkXatfQF1QRap-PQCx3kMfsKQCcxtkZqQ&sensor=true&key=AddYourOwnKeyHere

So, I tried this function:

function download_image1($image_url, $image_file){
    $fp = fopen ($image_file, 'w+');
    $ch = curl_init($image_url);
    // curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // enable if you want
    curl_setopt($ch, CURLOPT_FILE, $fp); // output to file
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT, 1000); // some large value to allow curl to run for a long time
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0');
    // curl_setopt($ch, CURLOPT_VERBOSE, true); // Enable this line to see debug prints
    curl_exec($ch);
    curl_close($ch); // closing curl handle
    fclose($fp); // closing file handle
}

download_image1($photo, "test.jpg");

.. where it $photocontains the request URL.

This does not work, it saves a blank image with header errors, perhaps because the request is not the actual URL of the photo. In addition, it is impossible to find out in the request URL which image extension I am going to get (jpg, png, gif, etc.), to make another problem.

Any help on saving photos is appreciated.

URL :

function get_furl($url)
    {
    $furl = false;
    // First check response headers
    $headers = get_headers($url);
    // Test for 301 or 302
    if(preg_match('/^HTTP\/\d\.\d\s+(301|302)/',$headers[0]))
        {
        foreach($headers as $value)
            {
            if(substr(strtolower($value), 0, 9) == "location:")
                {
                $furl = trim(substr($value, 9, strlen($value)));
                }
            }
        }
    // Set final URL
    $furl = ($furl) ? $furl : $url;
    return $furl;
    }
