How to upload files via FTP using PHP ?

In this tutorial, we are going to learn to upload files via FTP using PHP.

The File Transfer Protocol (FTP) is a standard communication protocol used for the transfer of computer files from a server to a client on a computer network. FTP is built on a client–server model architecture using separate control and data connections between the client and the server.

We will be using an in build PHP function : ftp_connect

ftp_connect(string $hostname, int $port = 21, int $timeout = 90): FTP\Connection|false

ftp_connect() opens an FTP connection to the specified hostname.

Parameters

hostname : The FTP server address. This parameter shouldn’t have any trailing slashes and shouldn’t be prefixed with ftp://

port : This parameter specifies an alternate port to connect to. If it is omitted or set to zero, then the default FTP port, 21, will be used.

timeout : This parameter specifies the timeout in seconds for all subsequent network operations. If omitted, the default value is 90 seconds.

Full Source Code to Upload File via FTP using PHP

<?php
function uploadFTP($server, $username, $password, $local_file, $remote_dir, $filename){
    // connect to server
    $connection = ftp_connect($server) or die("Couldn't connect to $server"); 

    // login
    if (@ftp_login($connection, $username, $password)){
        // successfully connected
    }else{
        echo 'connection failed';
        return false;
    }
    ftp_pasv($connection, true);
    ftp_put($connection, $remote_dir.$filename, $local_file, FTP_BINARY);
    ftp_close($connection);
    echo 'upload success';
    return true;
}


$server = '*****'; //FTP Host
$user = '*****'; //FTP Username
$password = '*****'; //FTP Password
$local_file = "*****"; //Path to Local File (example : C:/xampp/htdocs/ftp/image.jpeg)
$remote_dir = '*****'; //Path from FTP root to upload folder (example : /myFolder/subFolder/)
$filename_after_upload = '****'; //filename that will be given to uploaded file (example : abc.jpg)

uploadFTP($server, $user, $password, $local_file, $remote_dir, $filename_after_upload);
