Are there any best practices or specific guidelines to follow when including a favicon on a website using PHP?

When including a favicon on a website using PHP, it is best practice to place the favicon file in the root directory of your website and reference it in the HTML head section using a link tag. This ensures that the favicon is easily accessible and properly displayed across all pages of the website.

<!DOCTYPE html>
<html>
<head>
    <link rel="icon" type="image/png" href="/favicon.png">
    <title>Your Website Title</title>
</head>
<body>
    <!-- Your website content here -->
</body>
</html>
