Title: PHP script implementation of cross-server file transfer
1. Introduction
In cross-server file transfer, we usually need to transfer files from One server transmits to another server. This article will introduce how to use PHP scripts to implement cross-server file transfer on Linux servers, and give specific code examples.
2. Preparation work
Before starting to write PHP scripts, we need to ensure that the following environment has been configured on the server:
- Install PHP: on the Linux server Install PHP and ensure that the PHP version meets the code requirements.
- Set file directory permissions: Make sure the directory where the file is located has read and write permissions so that the file can be read and written.
- Configure SSH: Make sure that SSH key authentication has been configured between servers to enable secure file transfer between servers.
3. PHP script writing
The following is a simple PHP script example for cross-server file transfer on a Linux server:
<?php
// 源服務器信息
$sourceServer = array(
'host' => '源服務器IP地址',
'port' => 'SSH端口（默認22）',
'username' => '源服務器用戶名',
'password' => '源服務器密碼'
);
// 目標服務器信息
$targetServer = array(
'host' => '目標服務器IP地址',
'port' => 'SSH端口（默認22）',
'username' => '目標服務器用戶名',
'password' => '目標服務器密碼'
);
// 源文件路徑
$sourceFile = '/path/to/source/file';
// 目標文件路徑
$targetFile = '/path/to/target/file';
// 創(chuàng)建SSH連接（源服務器）
$sshSource = ssh2_connect($sourceServer['host'], $sourceServer['port']);
ssh2_auth_password($sshSource, $sourceServer['username'], $sourceServer['password']);
// 創(chuàng)建SSH連接（目標服務器）
$sshTarget = ssh2_connect($targetServer['host'], $targetServer['port']);
ssh2_auth_password($sshTarget, $targetServer['username'], $targetServer['password']);
// 執(zhí)行文件傳輸（從源服務器到目標服務器）
if (ssh2_scp_recv($sshSource, $sourceFile, $targetFile)) {
echo "文件傳輸成功";
} else {
echo "文件傳輸失敗";
}
// 關閉SSH連接
ssh2_disconnect($sshSource);
ssh2_disconnect($sshTarget);
?>In the code , we first defined the source server and target server information (IP address, SSH port, username, password), and then specified the source file path and target file path to be transferred.
Next, we create an SSH connection through the ssh2_connect function and authenticate through the ssh2_auth_password function.
Finally, we use the ssh2_scp_recv function to perform the file transfer operation and transfer the source file to the target server. If the transfer is successful, "File transfer successful" is output; otherwise, "File transfer failed" is output.
4. Summary
Through the above PHP script example, we can implement cross-server file transfer on the Linux server. In actual use, the code can be appropriately modified and optimized according to specific needs to meet your actual needs.
It should be noted that in order to ensure the security of file transfer, it is recommended to use SSH key authentication method for authentication and file transfer operations between servers.

Methods of changing umask There are two ways to change the current umask in PHP: Using the umask() function: The umask() function directly changes the current umask. Its syntax is: intumas
PHP server security settings: How to prohibit file downloads
Mar 10, 2024 pm 04:48 PM
PHP server security settings are an important part of website operation that cannot be ignored. Prohibiting file downloads is a key step to protect website data security. By setting some security measures in the PHP code, malicious users can be effectively prevented from obtaining sensitive information on the website by downloading files. This article will detail how to disable file downloads and provide specific PHP code examples. 1. Direct access to sensitive files is prohibited. Sensitive files stored in the website directory, such as database configuration files, log files, etc., should be prohibited from being accessed directly through the browser.
How to read text files in html
Mar 26, 2024 pm 04:07 PM
HTML itself cannot read text files directly, but this functionality can be achieved through back-end programming languages ??(such as PHP, Python, Java) or front-end JavaScript technology. The backend method uses PHP's file_get_contents() function to read the content from the text file and embed it into the HTML page. The front-end JavaScript method uses the Fetch API to send a GET request to a text file on the server, then parses the response content and displays it in an HTML page.
