php下载文件的代码为:

function download_file($url = '', $fileName = '')
{
	$ch = curl_init();
	$fp = fopen($fileName, 'wb');
	curl_setopt($ch, CURLOPT_URL, $url);
	curl_setopt($ch, CURLOPT_FILE, $fp);
	curl_setopt($ch, CURLOPT_HEADER, 0);
	curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
	curl_setopt($ch, CURLOPT_TIMEOUT, 60);
	curl_exec($ch);
	curl_close($ch);
	fclose($fp);
}

      那怎么从php服务下载到本地pc呢(上传可以用html的form表单)?   可以在php上写个test.php服务, 然后在浏览器访问test.php便是下载mp4, test.php内容为:

<?php

$result = file_get_contents("......mp4"); // 填写资源所在路径
header('Content-Type:application/octet-stream');
header('Content-Disposition:attachment; filename="download.mp4"');
echo $result;

?>
        试了一下, 靠谱。
