PHP FTP: A Comprehensive Guide

Introduction

FTP (File Transfer Protocol) is a standard network protocol used for the transfer of files between a client and a server on a computer network. PHP, being a versatile server-side scripting language, provides built-in support for FTP, allowing developers to interact with FTP servers programmatically. This guide will delve into the details of how to use PHP's FTP functions to manage files on an FTP server.

$connId = ftp_connect($ftpServer) or die("Could not connect to $ftpServer");

Once connected, you'll need to authenticate with the server using ftp_login()
