The code which I use:
我使用的代码：
$opts = array('http'=>array('header' => "User-Agent:Mozilla/5.0 (Windows NT 6.2) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.75 Safari/537.1\r\n", 'timeout' => "360"));
$context = stream_context_create($opts);
$imageString = file_get_contents(urldecode(urlencode($filename)), false, $context);
$save = file_put_contents(dirname(dirname(__FILE__)) . '/tmp/' . $id . '_' . $sequenceNumber . '.jpg', $imageString);
Anyone has a idea why I get a 500 error?
