How can PHP be integrated with HTML and CSS to create interactive elements on a website?

To integrate PHP with HTML and CSS to create interactive elements on a website, you can use PHP to dynamically generate HTML content based on user input or server-side data. This allows you to create dynamic websites that respond to user actions or database queries. By embedding PHP code within HTML files, you can generate dynamic content, handle form submissions, and interact with databases. Additionally, you can use PHP to generate CSS styles dynamically based on user preferences or server-side data. 

<!DOCTYPE html>
<html>
<head>
    <style>
        <?php
            // Generate CSS styles dynamically using PHP
            $color = "blue";
            echo "body { background-color: $color; }";
        ?>
    </style>
</head>
<body>
    <h1>Welcome to our website!</h1>
    
    <?php
        // Generate HTML content dynamically using PHP
        $name = "John";
        echo "<p>Hello, $name! This content is generated using PHP.</p>";
    ?>
    
    <form method="post">
        <input type="text" name="input_text">
        <input type="submit" value="Submit">
    </form>
    
    <?php
        // Handle form submissions using PHP
        if(isset($_POST['input_text'])){
            $input_text = $_POST['input_text'];
            echo "<p>You entered: $input_text</p>";
        }
    ?>
</body>
</html>
