答

function download_image ($url, $the_filename) {

    $cookie = tempnam ("/tmp", "CURLCOOKIE");
    $ch = curl_init ($url);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Debian) Firefox/0.10.1");
    curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie);
    curl_setopt($ch, CURLOPT_HEADER, false);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_BINARYTRANSFER,true);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);
    curl_setopt($ch, CURLOPT_MAXREDIRS, 5);
    curl_setopt($ch, CURLOPT_ENCODING, "");
    curl_setopt($ch, CURLINFO_EFFECTIVE_URL, true);
    curl_setopt($ch, CURLOPT_REFERER, "http://tomakefast.com");
    curl_setopt($ch, CURLOPT_POST, false);
    $rawdata=curl_exec($ch);
    curl_close($ch);
    file_put_contents("../somewhere/". $the_filename, $rawdata);

}

如果您发现任何问题，请告知我们。这偶尔给我一个0字节的图像文件，但这可能由于许多原因而发生。这可以改进以在0字节上返回false，甚至可以进行基本测试以查看是否确实下载了图像。

If you see any problems, please let me know. This occasionally gives me a 0 byte image file but that could happen for any number of reasons. This could be improved to return false on 0 bytes, maybe even do a basic test to see if indeed an image was downloaded.
