在PHP中保存来自url的图像

Question

I'm trying to save a image from following link. I've used cURL library and file_put_contents() function with no success. When I run the script, a HTTP error happens and the image is not saved. The link is: http://pocanga.cptec.inpe.br/repositorio5/goes12/goes12_web/no_realcada_alta/2012/01/S11219780_201201010015.jpg

$outputPath = "img/image.jpg";
file_put_contents($outputPath, file_get_contents($link));

Maybe file_get_contents() unfortunatelly doesn't accept url subdomain.

Answer 1

This works for me.

The header information did the trick. Otherwise it was putting a blank image.

$context = stream_context_create(array(
    'http' => array(
        'ignore_errors' => true,
        'header' => "User-Agent:MyAgent/1.0
"
     )
));

$url = 'http://pocanga.cptec.inpe.br/repositorio5/goes12/goes12_web/no_realcada_alta/2012/01/S11219780_201201010015.jpg';
$img = 'img.jpg';
file_put_contents($img, file_get_contents($url, FALSE, $context));
