PHP is a programming language that is hugely popular and rightly so. This language runs on web servers and is used to design dynamic websites that change each time a page is loaded. If you are looking to learn this language, you will find it to be flexible and easy to learn even if you have never written a line of code in your life before. If on the other hand you have been working with code and probably know another language, then you will almost certainly come across similarities with other programming languages. In fact if you are familiar with such languages like C, Java and Perl, you will find it pretty easy to adapt your existing programming skills and style to PHP with very little effort.

One of the things you will need to do if you will be running locally on your PC, is to install a web server. Like we said, PHP only runs on the server and displays the formatted results through your browser. Through your PHP training, you will first get acquainted with the basics of PHP. These include learning about the Variables, data types and the control statements that will form the core of the PHP language. Variables in PHP are simply containers that store values and are declared using the symbol $. For example, to declare a variable called ‘name’ that stores the value ‘David’, the following code is used.
$name = “David”
Here, we have declared the variable and given it a value.

In your PHP training, you will learn that a variable name is always prefixed with the $ sign. Once declared, you can also display the results of the variable using ‘echo’ as follows
$name = “David”
echo “Hi there, “;
echo $name
the output of this line of code is
Hi there, David
Your PHP training will also introduce you to PHP tags. We use the to tell PHP that every line of code between these 2 tags is PHP code rather than HTML and should thus be executed on the server and the results displayed on the browser. Thus our earlier code would look something like this on a .PHP file:
$name = “David”
echo “Hi there, “;
echo $name
?>
When this script is run from a web server, the results; “Hi there, David”, are displayed. You have just finished your basic PHP training. See how easy it is?
