<?php
//要使用的FTP服务器
$ftp_server = "ftp.example.com";
  
//FTP 连接的用户名
$ftp_user = "user";
  
//用户密码
$ftp_pass = "password";
  
//建立连接或者连接失败
$ftp = ftp_connect($ftp_server)
    or die("Could not connect to $ftp_server");
   
if($ftp) {
  echo "Successfully connected to $ftp_server!\n";
 
  //尝试登录
  if(@ftp_login($ftp, $ftp_user, $ftp_pass)) {
    echo "Connected as $ftp_user@$ftp_server\n";

    //服务器文件所在路径
    //需要追加的内容
    $server_file = "server_demo.txt";

    //本地文件路径
    //内容被采取追加
    $local_file = "local_demo.txt";
        
    //追加指定本地文件的内容
    if (ftp_append($ftp, $server_file, 
                $local_file, FTP_BINARY)) {
      echo "Successfully appended the content\n";
    } else {
      echo "Error while appending\n";
    }
    
  } else {
    echo "Couldn't connect as $ftp_user\n";
  }
 
  //关闭连接
  if(ftp_close($ftp)) {
    echo "Connection closed successfully!\n"; 
  } 
}
?> 

上述代码的输出将是:

Successfully connected to ftp.example.com!
Connected as user@ftp.example.com
Successfully appended the content
Connection closed successfully!
