What is SSL

SSL(Secure Sockets Layer)- It enables browsers to transmit data to and from a web server in a secure cryptographic way to make life hard for third party spies monitoring all internet traffic. When websites pages open with https( we have to install the SSL in our server. When we install SSL, we have to create the certificate (you have to pvoide some detail like countryCode, state, name, email etc during SSL created).

SSH (Secure Shell)-it enables a networked computer one to provide access to a shell on networked computer two. The user can have a level of confidence that spies listening to the insecure channel cannot decrypt data sent between the networked computer(s).

FTP(File Transfer Protocol)- Its protocol (rule) that is used when we need to tranfer a file from one location to another location(One server to another server).

SFTP(Secure File Transfer Protocol)-"FTP over SSH" uses the regular old FTP protocol, but an SSH tunnel is placed between client and server.

HTTPS (Hypertext Transfer Protocol Secure)- You have to install SSL Certificate to run your web pages as https

Question: cURL extension has to be loaded to use this, This error is coming when use run php through CLI, Its working fine when Running through browser. I am working on WampServer in window7. 

Answer: WAMP uses different php.ini files in the CLI and for Apache(Browser). when you enable php_openssl through the WAMP server, you enable it for Apache, not for the CLI. You need to modify C:\wamp\bin\php\php-5.5.x\php.ini to enable it for the CLI.
