What are some best practices for optimizing PHP code for readability and efficiency in templates or views?

When optimizing PHP code for readability and efficiency in templates or views, it is important to follow best practices such as using proper indentation, meaningful variable names, and avoiding unnecessary code repetition. Additionally, consider separating logic from presentation by using template engines like Twig or Blade.

<?php

// Example of optimized PHP code in a template using Twig

// Define variables with meaningful names
$username = 'John Doe';
$age = 30;

// Output the variables in the template
echo "Hello, $username. You are $age years old.";

?>
