ftp_put()函数是PHP中的一个内置函数，用于将文件上传到 FTP 服务器。
句法：

ftp_put( $ftp_connection, $remote_file_path, $local_file_path, $mode, $start_position );

参数：该函数接受上面提到的五个参数，如下所述：

$ftp_connection：必填参数。它指定用于上传文件的现有 FTP 连接。
$remote_file_path：必填参数。它指定远程服务器中的路径，即上传文件的 FTP 服务器。
$local_file_path：必填参数。它指定要上传到 FTP 服务器的文件的路径。
$mode：必填参数。它指定传输模式。参数的值是 FTP_ASCII 或 FTP_BINARY。
$start_position：可选参数。它指定远程文件中开始上传的位置。

返回值：成功时返回True，失败时返回False。
笔记：

此函数在PHP 4.0.0 及更新版本上可用。
以下示例无法在在线 IDE 上运行。因此，请尝试在一些PHP托管服务器或具有正确 ftp 服务器名称的 localhost 中运行。

下面的例子说明了 ftp_put()函数在PHP中的使用：
示例 1：

php

logged in successfully!";
          
        if (ftp_put($ftp_connection,
                "uploadedfile_name_in_server.txt", $file, FTP_ASCII))
        {
          echo "
Uploaded successful $file.";
        }
        else {
          echo "
Error while uploading $file.";
        }
           
    }
    else {
        echo "
login failed!";
    }
  
    // Closing the  connection
    if(ftp_close($ftp_connection)) {
        echo "
Connection closed Successfully!";
    }
}
?>

php

logged in successfully!";
         
        if (ftp_put($ftp_connection,
            "uploadedfile_name_in_server.txt", $file, FTP_ASCII))
        {
          echo "
Uploaded successful $file.";
        }
        else {
          echo "
Error while uploading $file.";
        }
    }
    else {
        echo "
login failed!";
    }
     
    // Echo ftp_get_option($ftp_connection, 1);
    // Closing  connection
    if(ftp_close($ftp_connection)) {
        echo "
Connection closed Successfully!";
    }
}
 
?>

输出：

Successfully connected to the ftp server!
logged in successfully!
Uploaded successful filetoupload.txt.
Connection closed Successfully!

示例 2：使用端口号 21 连接到 ftp 服务器，然后上传文件。

PHP

logged in successfully!";
         
        if (ftp_put($ftp_connection,
            "uploadedfile_name_in_server.txt", $file, FTP_ASCII))
        {
          echo "
Uploaded successful $file.";
        }
        else {
          echo "
Error while uploading $file.";
        }
    }
    else {
        echo "
login failed!";
    }
     
    // Echo ftp_get_option($ftp_connection, 1);
    // Closing  connection
    if(ftp_close($ftp_connection)) {
        echo "
Connection closed Successfully!";
    }
}
 
?>

输出：

Successfully connected to the ftp server!
logged in successfully!
Uploaded successful filetoupload.txt.
Connection closed Successfully!
