cURL +通过浏览器下载文件

Question

当我使用cURL下载某个文件时，cURL会将文件打印到浏览器。但是我想打开'保存到'浏览器下载窗口。我怎样才能做到这一点？

$c = curl_init(); 
curl_setopt($c, CURLOPT_URL, $url); 
curl_setopt($c, CURLOPT_POSTFIELDS, "file_name=test.rar"); 
curl_setopt($c, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($c, CURLOPT_FOLLOWLOCATION, true); 
curl_exec($c); 
curl_close($c); 

Answer 1

ini_set('memory_limit','128M'); 
$content = curl_exec($c); 
curl_close($c); 

header('Content-Description: File Transfer'); 
header('Content-Type: application/octet-stream'); 
header('Content-Disposition: attachment; filename=your_file.txt'); 
header('Content-Transfer-Encoding: binary'); 
header('Expires: 0'); 
header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); 
header('Pragma: public'); 
header('Content-Length: ' . strlen($content)); 
ob_clean(); 
flush(); 
echo $content; 
flush();
