The PHP programming language provides several ways to generate text.

The echo keyword is the most common way.

In a PHP-based web application, generated text becomes part of the response that the web server return to the client.

A simple echo:

<?php
echo "Hello World";
?>

You can use echo with multiple parameters, to combine text and variables.

The example below uses two variables named $word1 and $word2.

<?php
$word1 = "Hello";
$word2 = "World";
echo $word1, " ", $word2;
?>

PHP also provides a shortcut for echo:

$msg = "Hello World";
This is HTML, lorem ipsum, <?= $msg ?>, more HTML etc.
