使用 PHP 下载远程文件到服务器 [英] Download Remote File to Server with PHP

问题描述

过去两天我一直在四处寻找并尝试了所有方法，但仍然无法正常工作.我觉得这应该是一件比较简单的事情.

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.

我想要做的就是将远程文件从 URL 下载到我服务器上的目录.

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

例如，如果

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

和 $_dir =/www/downloads/

然后当一切都说完了我想要1306495040_Number_Blink_1.1.1.apk在/www/downloads/

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

我试过 copy() 函数，我试过

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

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！

推荐答案

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();

// 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.
