In this tutorial, we will learn Hello World Program In PHP. In the last tutorial, we learnt how to install and start the virtual server in PC to run PHP code. Here we will learn basic PHP Syntax and learn how we can write Hello World program in PHP.
First of all, we will create a folder in htdocs folder to save our PHP files. I am creating a folder named PHPTutorials. You can see it in the image given below.
In this PHPTutorials folder, we will create a file “HelloWorld.php”. Always keep in mind save every file in PHP with .php extension.
Note! You can use any text editor to write PHP code like Notepad, Notepad++, Sublime Text. We will use here Sublime Text.
Basic PHP code Syntax:
To keep PHP code separate from HTML and CSS we have to write PHP code in Canonical PHP tags () mean we will write whole PHP code inside these tags. Now we will see an example of the Hello World program.
<?php echo "Hello World..."?>
As you can see we have written our PHP code inside Canonical PHP tags which keep it separate from rest of code. we have used echo to show output on the screen which is Hello World. Now please save this file as HelloWorld.php in PHPTutorials folder. After saving it we will run this code in the browser.
Note! Please keep your xampp server on to run PHP Code.
To run code make sure your XAMPP server is on then type this localhost/PHPTutorials/HelloWorld.php chrome address URL bar and hit enter. You will see output like this.
