使用PHP下载大型文件时服务器失败 [英] Server fails when downloading large files with PHP

问题描述

我正在使用 PHPSecLib 的SFTP功能从FTP服务器下载文件。

I'm using the SFTP functions of PHPSecLib to download files from an FTP server.

行

$sftp->get($fname);

如果文件最多可达200​​MB，但如果是300MB，浏览器会以Firefox can在[download.php]找不到该文件。也就是说，它说它找不到用于下载远程文件的php文件。

works if the file is up to 200MB, but if it's 300MB, the browser responds with "Firefox can't find the file at [download.php]". That is, it says it can't find the php file I use for downloading the remote file.

起初我以为这是由于$ code > memory_limit 设置在php.ini中，但如果设置为128M或350M，则无关紧要; 200MB文件仍然可以工作，300MB文件失败。而且在十秒钟后失败，所以 max_execution_time 或 max_input_time 似乎不是罪魁祸首。什么可能是错的？

At first I thought this was due to the memory_limit setting in php.ini, but it doesn't matter if it's set to 128M or 350M; 200MB files still work, and 300MB files fail. And it fails after ten seconds, so max_execution_time or max_input_time don't seem to be the culprits. What could be wrong?

推荐答案

还有什么可以做的...

Something else you could do...

<?php
include('Net/SFTP.php');

$sftp = new Net_SFTP('www.domain.tld');
$sftp->login('username', 'password');

$start = 0;
while (true) {
    $response = $sftp->get('1mb', false, $start, 1024);
    $start+= 1024;
    if (empty($response)) {
        break;
    }
    echo $response;
}

ie。下载多个块的文件。

ie. download the file in multiple chunks.
