What are the drawbacks of using inline JavaScript code within PHP files for dynamic content display?

Using inline JavaScript code within PHP files can lead to code readability issues, maintenance difficulties, and potential security vulnerabilities. To solve this problem, it is recommended to separate JavaScript code from PHP code by using external JavaScript files and properly integrating them into the PHP files. 

// PHP file with external JavaScript file integration
<html>
<head>
    <title>Dynamic Content Display</title>
    <script src="script.js"></script>
</head>
<body>
    <?php
    // PHP code for dynamic content display
    $dynamic_content = "Hello, World!";
    echo "<div id='dynamic-content'>$dynamic_content</div>";
    ?>
</body>
</html>
