PHP从Google地图获取文件并将其返回

I'm developing a web-service in PHP where I generate a URL for google static maps
For example:

http://maps.googleapis.com/maps/api/staticmap?center=Berkeley,CA&zoom=14&size=400x400&sensor=false

I need to get that png image and return it as image:

$fullURL = 'http://maps.googleapis.com/maps/api/staticmap?center=Berkeley,CA&zoom=14&size=400x400&sensor=false';
$img = file_get_contents($fullURL);
header("Content-Type: image/png");
header("Content-Length: " . filesize($img));
echo $img;

when I run the google url in browser I see the image and get: enter image description here

but when I run my page with the code above I don't see the image and it's size is different: enter image description here

How to do that right?
(my service suppose to return the same as google original url, png file).

    I think the problem is that you're using filesize() on the image content. Try using strlen() or similar:

    $fullURL = 'http://maps.googleapis.com/maps/api/staticmap?center=Berkeley,CA&zoom=14&size=400x400&sensor=false';
    $img = file_get_contents($fullURL);
    header("Content-Type: image/png");
    header("Content-Length: " . strlen($img));
    echo $img;
