In today’s world with so many third-party integrations and content-sharing, it’s important to understand and make use of protocols like SCP and SFTP. PHP’s SSH2 extension, a wrapper for libssh2 which implements the SSH2 protocol, provides several functions you can use to securely transfer files. – “Using SSH and SFTP with PHP” by Jamie Munroe
Jamie Munroe explains how you can set up a SSH & SFTP service using PHP.
SSH(Secure Shell) is a network protocol for secure data communication, remote shell services or command execution that is a network service between two networked computers over a secure channel(using SSH server and SSH client program).
SFTP(SSH File Transfer Protocol) is a replacement for FTP which provides an encrypted connection between the client and server for file transfer.
I have a dedicated server that I use; I have programs to help me communicate to the server in retrieving information about the server and the data on it. I use an SSH client called PuTTY; run command lines to install/delete/move items. SFTP/FTP client I use is FileZilla & Cyberduck; either programs can allow me to login as an SFTP/FTP client to my server, in which I can manipulate directories and files on the server.
Getting to the point on which why I find this article is very interesting to share is that you can connect to an SSH service using PHP. Perform basic commands, for example; create or rename directories, send and receive files from the server. Even setting up SSH keys all being run from PHP scripts.
