Are there any specific file extensions or naming conventions to follow when working with PHP and HTML files together?

When working with PHP and HTML files together, it is common to use the ".php" file extension for files that contain PHP code mixed with HTML. This allows the server to recognize and process the PHP code within the file. Additionally, it is a good practice to use a naming convention that reflects the purpose of the file, such as naming files that primarily contain PHP code with a ".php" extension and files that primarily contain HTML code with a ".html" extension. 

// Example of a PHP file with mixed PHP and HTML code using the ".php" extension
// file: index.php

<!DOCTYPE html>
<html>
<head>
    <title>PHP and HTML Example</title>
</head>
<body>
    <h1>Welcome to our website!</h1>
    
    <?php
    // PHP code to display current date
    echo "Today's date is " . date("Y-m-d");
    ?>
</body>
</html>
