使用PHP将远程文件下载到服务器 [英] Download Remote File to Server with PHP

问题描述

在过去的两天中，我一直在寻找所有的地方，尝试所有的事情，仍然无法获得任何工作。我觉得这应该是一件比较简单的事情。

我想做的是将远程文件从URL下载到我的服务器上的目录。 p>

所以，例如，如果

  $ _ url = http：// www.freewarelovers.com/android/download/temp/1306495040_Number_Blink_1.1.1.apk 
  

和 $ _ dir = / www / downloads /

然后当所有的说完，我想要$ code> 1306495040_Number_Blink_1。 1.1.apk 在 / www / downloads /

code> copy（）函数，我试过

  file_put_contents（$ _ dir 。$ _ file_name，file_get_contents（$ _ url））; 
  

并得到以下错误：

file_get_contents（）：无法打开流：HTTP请求失败！

解决方案

应该这样做：

  set_time_limit（0）; 
 
 $ url ='http://www.freewarelovers.com/android/download/temp/1306495040_Number_Blink_1.1.1.apk'; 
 $ file = fopen（dirname（__ FILE__）。'/downloads/a.apk'，'w +'）; 
 
 $ curl = curl_init（$ url）; 
 
 //更新PHP 5.4数组（）可以写成[] 
 curl_setopt_array（$ curl，[
 CURLOPT_URL => $ url，
 // CURLOPT_BINARYTRANSFER => 1，---没有PHP 5.1.3的影响
 CURLOPT_RETURNTRANSFER => 1，
 CURLOPT_FILE => $ file，
 CURLOPT_TIMEOUT => 50，
 CURLOPT_USERAGENT =>'Mozilla / 4.0（兼容; MSIE 5.01; Windows NT 5.0）'
]）; 
 
 $ response = curl_exec（$ curl）; 
 
 if（$ response === false）{
 //更新为PHP 5.3使用Namespaces异常（）成为\Exception（）
 throw new \Exception （'Curl error：'。curl_error（$ curl））; 
} 
 
 $ response; //做某事与回应。 
  

I've been looking all over the place for the last two days and trying everything and still can't get anything to work. I feel like this should be a relatively simple thing to do.

All I want to do is download a remote file from a URL to a directory on my server.

So, for example, if

$_url = http://www.freewarelovers.com/android/download/temp/1306495040_Number_Blink_1.1.1.apk

and $_dir = /www/downloads/

Then when all is said and done I want 1306495040_Number_Blink_1.1.1.apk in /www/downloads/

I've tried the copy() function, I've tried

file_put_contents("$_dir.$_file_name", file_get_contents($_url));

and get the following error:

file_get_contents(): failed to open stream: HTTP request failed!

解决方案

This should do it :

set_time_limit(0);

$url = 'http://www.freewarelovers.com/android/download/temp/1306495040_Number_Blink_1.1.1.apk';
$file = fopen(dirname(__FILE__) . '/downloads/a.apk', 'w+');

$curl = curl_init($url);

// Update as of PHP 5.4 array() can be written []
curl_setopt_array($curl, [
    CURLOPT_URL            => $url,
//  CURLOPT_BINARYTRANSFER => 1, --- No effect from PHP 5.1.3
    CURLOPT_RETURNTRANSFER => 1,
    CURLOPT_FILE           => $file,
    CURLOPT_TIMEOUT        => 50,
    CURLOPT_USERAGENT      => 'Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)'
]);

$response = curl_exec($curl);

if($response === false) {
    // Update as of PHP 5.3 use of Namespaces Exception() becomes \Exception()
    throw new \Exception('Curl error: ' . curl_error($curl));
}

$response; // Do something with the response.
