如何使用php从另一台服务器打开txt文件

Question

I want to open and write a txt file from another server, but I don't know how to do it? Can anyone help me?

<?PHP
   $fname=$_POST["fname"];

   $groupid=$_POST["groupid"];
   $myfile = fopen("Ji.txt", "a+") or die("Unable to open file!");
   fwrite($myfile, $fname."|".$groupid."
");
   fclose($myfile)
?>

I want to replace Ji.txt with http://xxx.xxx.xx.x/ddd.txt

</div>

Alternatively you can do it with the FTP functions

<?php
// Connect to remote FTP server
$conn = ftp_connect("ftp.example.com")or die("Cant connect to ftp server");
$login = ftp_login($conn, "username", "password");

// Open local (temporary) file handle
$fh = fopen("Ji.txt", "a+");

// Get remote file and save it to the previous file handle
if(ftp_fget($conn, $fh, "Ji.txt", FTP_ASCII))
{
    // Local file has now been updated with the content of the remote Ji.txt
    $fname = $_POST['fname'];
    $groupid = $_POST['groupid'];
    fwrite($fh, $fname.'|'.$groupid.'
');
    if(ftp_fput($conn, "Ji.txt", $fh, FTP_ASCII))
        echo 'File saved to remote server';
    else
        echo 'Error saving to remote server';
}
else
    echo 'Error downloading remote file';

ftp_close($conn);
fclose($fh);
?>
