Are there alternative methods, such as using variables or templates, to improve the readability and maintainability of PHP code with echo statements?

Using variables or templates can improve the readability and maintainability of PHP code with echo statements by separating the content from the presentation logic. By assigning content to variables or using templates, it becomes easier to manage and update the output without mixing it with PHP code.

// Using variables to improve readability and maintainability
$title = "Hello, World!";
$content = "This is a sample content.";

echo "<h1>{$title}</h1>";
echo "<p>{$content}</p>";
