What are the advantages of using templates or collecting output in variables to control content output in PHP?

Using templates or collecting output in variables helps to separate the presentation logic from the business logic in PHP applications. This approach makes the code more maintainable, reusable, and easier to understand. Templates allow for easier customization of the output without having to modify the underlying logic.

<?php

// Using templates to control content output
$template = "<h1>Hello, <?php echo $name; ?></h1>";
$name = "John Doe";

echo $template;

?>
