如果您
allow_url_fopen设置为
true：
$url = 'http://example.com/image.php';$img = '/my/folder/flower.gif';file_put_contents($img, file_get_contents($url));
其他使用cURL：
$ch = curl_init('http://example.com/image.php');$fp = fopen('/my/folder/flower.gif', 'wb');curl_setopt($ch, CURLOPT_FILE, $fp);curl_setopt($ch, CURLOPT_HEADER, 0);curl_exec($ch);curl_close($ch);fclose($fp);
