如何使用 PHP 从 SFTP 下载文件？

我正在尝试使用 php 从 sftp 服务器下载文件，但找不到任何正确的文档来下载文件。

<?php 
$strServer = "pass.com"; 
$strServerPort = "22";
$strServerUsername = "admin"; 
$strServerPassword = "password";
$resConnection = ssh2_connect($strServer, $strServerPort);
if(ssh2_auth_password($resConnection, $strServerUsername, $strServerPassword)) {
    $resSFTP = ssh2_sftp($resConnection);
    echo "success";
}
?>

打开 SFTP 连接后，我需要做什么才能下载文件？

原文

I am trying to download a file from an sftp server using php but I can't find any correct documentation to download a file.

<?php 
$strServer = "pass.com"; 
$strServerPort = "22";
$strServerUsername = "admin"; 
$strServerPassword = "password";
$resConnection = ssh2_connect($strServer, $strServerPort);
if(ssh2_auth_password($resConnection, $strServerUsername, $strServerPassword)) {
    $resSFTP = ssh2_sftp($resConnection);
    echo "success";
}
?>

Once I have the SFTP connection open, what do I need to do to download a file?

使用 phpseclib，一个纯 PHP SFTP 实现：

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

$sftp = new Net_SFTP('www.domain.tld');
if (!$sftp->login('username', 'password')) {
    exit('Login Failed');
}

// outputs the contents of filename.remote to the screen
echo $sftp->get('filename.remote');
?>

Using phpseclib, a pure PHP SFTP implementation:

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

$sftp = new Net_SFTP('www.domain.tld');
if (!$sftp->login('username', 'password')) {
    exit('Login Failed');
}

// outputs the contents of filename.remote to the screen
echo $sftp->get('filename.remote');
?>

打开 SFTP 连接后，您可以使用标准 PHP 函数读取文件并进行写入，例如 fopen 、fread 和 fwrite。您只需使用 ssh2.sftp:// 资源处理程序即可打开远程文件。

下面是一个示例，它将扫描目录并下载根文件夹中的所有文件：

// Assuming the SSH connection is already established:
$resSFTP = ssh2_sftp($resConnection);
$dirhandle = opendir("ssh2.sftp://$resSFTP/");
while ($entry = readdir($dirhandle)){
    $remotehandle = fopen("ssh2.sftp://$resSFTP/$entry", 'r');
    $localhandle = fopen("/tmp/$entry", 'w');
    while( $chunk = fread($remotehandle, 8192)) {
        fwrite($localhandle, $chunk);
    }
    fclose($remotehandle);
    fclose($localhandle);
}

Once you have your SFTP connection open, you can read files and write using standard PHP functions such as fopen, fread, and fwrite. You just need to use the ssh2.sftp:// resource handler to open your remote file.

Here is an example that will scan a directory and download all files in the root folder:

// Assuming the SSH connection is already established:
$resSFTP = ssh2_sftp($resConnection);
$dirhandle = opendir("ssh2.sftp://$resSFTP/");
while ($entry = readdir($dirhandle)){
    $remotehandle = fopen("ssh2.sftp://$resSFTP/$entry", 'r');
    $localhandle = fopen("/tmp/$entry", 'w');
    while( $chunk = fread($remotehandle, 8192)) {
        fwrite($localhandle, $chunk);
    }
    fclose($remotehandle);
    fclose($localhandle);
}
