“Hello World.” is the first program most beginning programmers will learn to write in any given language. Here is an example of how to print “Hello World!” in PHP.

Basic PHP Syntax

  • A PHP script can be placed anywhere in the document.
  • A PHP script starts with <?php and ends with ?>
  • The default file extension for PHP files is “.php”.
  • A PHP file normally contains HTML tags, and some PHP scripting code.

Below, we have an example of a simple PHP file, with a PHP script that uses a built-in PHP function “echo” to output the text “Hello World!” on a web page.

<?php
  echo "Hello World!";
?>

<!DOCTYPE html>
<html>
<body>
<h1>My first PHP page</h1>
  <?php
    echo "Hello World!";
  ?>
</body>
</html>

<?php
  echo "Hello World!";
  echo "<br/>";
  echo "PHP is so easy!";
  echo "<br/><h2>Rubbishguru</h2>";
?>

Note: PHP statements end with a semicolon (;).
