PHP는 URL을 기반으로 이미지를 다운로드합니다.

function imagefromURL($image,$rename)
{
$ch = curl_init($image);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
$rawdata=curl_exec ($ch);
curl_close ($ch);
$fp = fopen("$rename",'w');
fwrite($fp, $rawdata);
fclose($fp);
}

用法：

$url = "http://img.it-home.org/data/attachment/forum/2016pic2/logo.png";
$rename = "koonk.png";
imagefromURL($url,$rename);
?>
