用php将文件从一台服务器复制到另一台服务器

<?php
// 源服务器信息
$sourceServer = array(
    'host' => 'source_server_ip',
    'username' => 'source_server_username',
    'password' => 'source_server_password',
    'file' => '/path/to/source/file.txt'
);

// 目标服务器信息
$targetServer = array(
    'host' => 'target_server_ip',
    'username' => 'target_server_username',
    'password' => 'target_server_password',
    'file' => '/path/to/target/file.txt'
);

// 从源服务器读取文件内容
$sourceContent = file_get_contents('ssh2.sftp://' . ssh2_connect($sourceServer['host']) . $sourceServer['file']);

// 将文件内容发送到目标服务器
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://' . $targetServer['host'] . '/upload.php');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, array(
    'file' => $sourceContent
));
curl_exec($ch);
curl_close($ch);

// 在目标服务器上创建新文件并写入文件内容
file_put_contents('ssh2.sftp://' . ssh2_connect($targetServer['host']) . $targetServer['file'], $sourceContent);
?>
