Free PHP Tutorial

PHP is a scripting language that has the ability to output HTML. Instead of manually writing HTML files, you can program PHP to automatically generate them for you.

Did you know that every page generated on this website is a because of a single php script? This means that when a new page is added, there’s no need to manually create an HTML file. The PHP script generates it.

and it will make easier for us to manage pages. If it was the old-time when we have to write coding for html and generate each create a new set of codes for each page then it would be more difficult. Now PHP have made it easier for us to manage and develop the websites.

PHP and HTML

PHP scripts are embedded inside HTML files. The start of a PHP script is indicated by <?php and the end is indicated by ?>. When a script is run, it’s replaced in the HTML by its output. For example, the following PHP script outputs the text ‘Hello’:

<?php echo 'Hello'; ?>

The above PHP script will be replaced by its output. So the resulting HTML is this:

Hello

There can be an unlimited number of PHP scripts in an HTML file, and they can be placed anywhere inside the file.

However, HTML files that contain PHP use the file extension .php, rather than the usual.html. This is so that the PHP interpreters on web servers know that the file contains PHP code to be executed.

PHP Include

One of the useful features of PHP is its ability to include files inside other files.

Many websites use the same header on every page of their site. With PHP, they can write their header in a separate HTML file called header.html, and have PHP ‘include’ the contents of this file on every other page. They do this by writing the following code where they want the header to go:

<?php include('header.html'); ?>

This way, when they want to edit their header, they only need to edit their header.html file once and the changes are made on every page.
