PHP is a server scripting language and a tool for making dynamic and interactive websites. Before you get into learning PHP, you’ll need a little HTML, CSS, and JavaScript. To this end, I wanted to put together an article the shared an overview of learning PHP in the hopes that it might help beginners gain a foothold in the world of PHP.

What is PHP?

PHP is an acronym for “PHP: Hypertext Preprocessor” and can run on a webserver

How to install PHP

PHP Syntax

A PHP script can be placed anywhere in a PHP file as long as it looks like this:

<?php 

//Scripts go here
?>

You can save a PHP file as FileName.php

Comments

In Php, you can create a comment by using double slashes (as in the script above).

Variables in PHP

In PHP, all variables start with a dollar sign followed by the name of the variable. If you want to assign a value to the variable you can do it as shown below:

<?php 

 $variable_1 = 1;
 $greeting = "Hello World";
?

If you want to concatenate two variables, you can do this by using the ‘.’

<?php

$var1 = "Hello";
$var2 = "World";
$var3 = $var1 . $var2;
echo $var3;
//Will output: Hello World
?>

If you want to add two numbers, you need to use ‘+’ if you use ‘’ you will end up with the two numbers next to each other.

Output text

In PHP, you can use either an ‘Echo’ statement or a ‘Print’ statement. Examples of Echo and Print statements can be seen below:

<?php 

$var = "Hello World";
echo $var;
//Output will be: Hello World!
print $var;
//Output will be: Hello World
?>
