需要php脚本来在远程服务器上下载文件并在本地保存 [英] Need php script to download a file on a remote server and save locally

问题描述

尝试在远程服务器上下载文件并将其保存到本地子目录。

以下代码似乎适用于小文件， 1MB，但较大的文件只是超时，甚至没有开始下载。

 <？php 
 
 $ source =http://someurl.com/afile.zip; 
 $ destination =/asubfolder/afile.zip; 
 
 $ data = file_get_contents（$ source）; 
 $ file = fopen（$ destination，w +）; 
 fputs（$ file，$ data）; 
 fclose（$ file）; 
 
？>任何有关如何下载较大文件而不中断的建议？
 
 
 $ b class =h2_lin>解决方案
 
  $ ch = curl_init（）; 
 $ source =http://someurl.com/afile.zip; 
 curl_setopt（$ ch，CURLOPT_URL，$ source）; 
 curl_setopt（$ ch，CURLOPT_RETURNTRANSFER，1）; 
 $ data = curl_exec（$ ch）; 
 curl_close（$ ch）; 
 
 $ destination =/asubfolder/afile.zip; 
 $ file = fopen（$ destination，w +）; 
 fputs（$ file，$ data）; 
 fclose（$ file）; 
  
 
Trying to download a file on a remote server and save it to a local subdirectory.

The following code seems to work for small files, < 1MB, but larger files just time out and don't even begin to download.
<?php

 $source = "http://someurl.com/afile.zip";
 $destination = "/asubfolder/afile.zip";

 $data = file_get_contents($source);
 $file = fopen($destination, "w+");
 fputs($file, $data);
 fclose($file);

?>
Any suggestions on how to download larger files without interruption?
解决方案
$ch = curl_init();
$source = "http://someurl.com/afile.zip";
curl_setopt($ch, CURLOPT_URL, $source);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec ($ch);
curl_close ($ch);

$destination = "/asubfolder/afile.zip";
$file = fopen($destination, "w+");
fputs($file, $data);
fclose($file);
