01 - Text Output Using PHP

Hello World!

As far as possible, PHP processing (business rules) should be carried out before the <head> tag on a web page. In the <body> of the page, there should only be echo, include and other output statements.

Homework: Write your own version of the "Hello World!" program. It should display several pieces of text and should include formatting tags such as headings and paragraphs.


<!-- Here is the page source code for 01hello.php -->

<?php
  include "code.php";    // Contains the function used to display
                         // the source code of web pages.
  
  $helloMessage = "<h3>Hello World!</h3>";
?>
