What are the potential pitfalls of using inline CSS in PHP code?

Using inline CSS in PHP code can lead to a lack of separation of concerns, making it harder to maintain and update the code in the future. It can also make the code less reusable and harder to debug. To avoid these pitfalls, it's recommended to separate the CSS styles into external stylesheets and link them to the HTML markup. 

<!DOCTYPE html>
<html>
<head>
    <link rel="stylesheet" type="text/css" href="styles.css">
</head>
<body>
    <h1 style="color: blue;">Hello, World!</h1>
</body>
</html>
