What are some best practices for incorporating HTML and JavaScript within PHP scripts?

When incorporating HTML and JavaScript within PHP scripts, it is important to maintain separation of concerns to keep the code clean and easily maintainable. One common practice is to use PHP to generate dynamic content and then output it within HTML tags. Additionally, you can use PHP to conditionally include or execute JavaScript code based on certain conditions. 

<?php
// PHP code to generate dynamic content
$dynamic_content = "Hello, world!";

// Output HTML with dynamic content
echo "<h1>$dynamic_content</h1>";

// Conditionally include JavaScript based on a condition
if ($dynamic_content === "Hello, world!") {
    echo '<script>alert("Dynamic content is Hello, world!");</script>';
}
?>
