使用 curl 下载大文件 [英] Downloading a large file using curl

问题描述

我需要使用 curl 下载远程文件.

I need to download remote file using curl.

这是我的示例代码:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$st = curl_exec($ch);
$fd = fopen($tmp_name, 'w');
fwrite($fd, $st);
fclose($fd);

curl_close($ch);

但它不能处理大文件，因为它先读到内存.

But it can't handle big files, because it reads to memory first.

是否可以将文件直接流式传输到磁盘?

Is it possible to stream the file directly to disk?

推荐答案

<?php
set_time_limit(0);
//This is the file where we save the    information
$fp = fopen (dirname(__FILE__) . '/localfile.tmp', 'w+');
//Here is the file we are downloading, replace spaces with %20
$ch = curl_init(str_replace(" ","%20",$url));
curl_setopt($ch, CURLOPT_TIMEOUT, 50);
// write curl response to file
curl_setopt($ch, CURLOPT_FILE, $fp); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
// get curl response
curl_exec($ch); 
curl_close($ch);
fclose($fp);
?>
