How to move and copy files on FTP server using PHP

Introduction:
FTP (File Transfer Protocol) is a standard protocol for transferring files between different computers. In web development, it is often necessary to move or copy files from an FTP server. This article will introduce how to use PHP to move and copy files on an FTP server.

1. Connect to the FTP server
Before any interaction with the FTP server, we need to connect to the FTP server first. The FTP extension using PHP provides a way to use FTP functionality.

// 连接FTP服务器
$ftp_server = "ftp.example.com";
$ftp_username = "username";
$ftp_password = "password";

$conn_id = ftp_connect($ftp_server) or die("无法连接到FTP服务器");

// 登录FTP服务器
$login_result = ftp_login($conn_id, $ftp_username, $ftp_password);

if (!$login_result) {
    die("无法登录到FTP服务器");
}

// 设置FTP服务器模式
ftp_pasv($conn_id, true);

2. Moving files
Moving files is the operation of moving files from one directory to another. Use the ftp_rename function to move files on the FTP server.

// 移动文件
$source_file = "/source_directory/file.txt";
$destination_file = "/destination_directory/file.txt";

if (ftp_rename($conn_id, $source_file, $destination_file)) {
    echo "文件移动成功";
} else {
    echo "文件移动失败";
}

3. Copy files
Copying files is the operation of copying files from one directory to another directory. Use the ftp_get and ftp_put functions to copy files on the FTP server.

// 复制文件
$source_file = "/source_directory/file.txt";
$destination_file = "/destination_directory/file.txt";

// 从FTP服务器下载文件
if (ftp_get($conn_id, $destination_file, $source_file, FTP_BINARY)) {
    echo "文件复制成功";
} else {
    echo "文件复制失败";
}

// 将文件上传到FTP服务器
if (ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY)) {
    echo "文件复制成功";
} else {
    echo "文件复制失败";
}

4. Close the FTP connection
After completing all interactions with the FTP server, we need to close the connection with the FTP server.

// 关闭FTP连接
ftp_close($conn_id);

Conclusion:
This article introduces how to use PHP to move and copy files on an FTP server. By connecting to the FTP server, using the corresponding functions to move and copy files, and finally closing the connection to the FTP server, these operations can be flexibly applied in web development.
