Why is PHP popular?
• PHP is extremely simple for a newcomer, but offers many advanced features for a professional
• PHP code is enclosed in special start and end processing tags that allow you to jump into and out
of “PHP mode”, to implement instructions within an HTMLdocument.
• PHP code is executed on the server (“server-side”), unlike JavaScript code that is executed in the
browser (“client-side”). The client receives the results of running the script without knowing what the
underlying code was. Recently, server-side has become to be known as “The Cloud”.
