下面的示例显示了 ftp_rename( ) 函数。

<?php
//要使用的FTP服务器
$ftp_server = "ftp.example.com";
 
$old_file = 'oldfile.txt';
$new_file = 'newfile.txt';

//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";

    //尝试将 $old_file 重命名为 $new_file
    if (ftp_rename($ftp, $old_file, $new_file)) {
      echo "Successfully renamed $old_file to $new_file\n";
    } else {
      echo "Error while renaming $old_file to $new_file\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 renamed oldfile.txt to newfile.txt
Connection closed successfully!
