Hi Reader's,
Welcome to FindNerd, today we are going to discuss how to use ftp_size() function in php ?
The ftp_size() function is used for returning the size of a specified file on the FTP server.
This function returns the file size in bytes on success, or -1 on error

syntax of ftp_size() function

ftp_size(ftp_connection,file);

ftp_connection is a required parameter
file is a required parameter

you can see bellow example:

<?php
//here call username and password
$username="test"
$userpass=12345;
// connect and login to FTP server

$ftp_server = "ftp.live.com";
$conn = ftp_connect($ftp_server) or die("Could not connect to $ftp_server");
$login = ftp_login($conn, $username, $userpass);

$file = "file.txt";

// get size of $file
$filesize = ftp_size($conn, $file);
//check file size
if ($filesize != -1)
  {
  echo "$file is $fsize bytes.";
  }
else
  {
  echo "Error getting file size.";
  }

//here close connection
ftp_close($conn);
?>
