Introduction
PHP is one of the most popular server-side scripting
languages in existence today. The language has the ability to
communicate back and forth with a server and create a dynamic web page
for the user. If you have a web hosting account to run your personal
blog or website, I can guarantee that PHP is already installed. Even the
page you are looking at right now was created by PHP. If you have
ambitions of becoming a web developer, PHP is a must for you and will
allow you to create dynamic web pages based on external input, usually
from the user. It is also important to note that PHP is an
object-oriented programming language, and O.O.P. is one of the things we
will cover in the series.
PHP is not the language to jump straight into if you have had no
experience at all. Getting a grasp of the basic programming concepts
might be easier in a language such as Visual Basic as the syntax and
concepts in PHP might be quite confusing for a beginner. If you have no
experience in scripting, I might also suggest taking a look at
JavaScript which is a client-side scripting
language, making it limited when compared to PHP. But don’t let that
scare you, PHP teaches some great coding habits and if you are capable
of picking things up quickly then you should be just fine. Let’s take a
little look at the syntax first, here’s how you would tell PHP to output
the text “Welcome to my website” to a browser:
<?php echo 'Welcome to my website'; ?>
It all looks pretty logical, right? You are echoing out the sentence
enclosed in the quotation marks to the web browser. And each statement
in PHP must end with a “;” to notify the processor module that we have
ended our statement. New lines and blank space are not recognised. You
must also wrap PHP code inside “<?php” and “?>” tags to notify the
server when a PHP script will start and end. So if you think you are
