What are the potential pitfalls of trying to echo a graphic directly in PHP?

Echoing a graphic directly in PHP can lead to potential issues such as inefficient performance, lack of flexibility in styling, and difficulty in maintaining the code. To solve this, it is recommended to separate the HTML markup from the PHP logic by using a template engine like Twig or Blade. This allows for better organization, easier maintenance, and improved readability of the code. 

<?php
// Example using Twig template engine
require_once 'vendor/autoload.php';

$loader = new \Twig\Loader\FilesystemLoader('templates');
$twig = new \Twig\Environment($loader);

// Render the template with the graphic
echo $twig->render('graphic.html', ['graphic' => 'path/to/graphic.png']);
?>
