What potential pitfalls should PHP beginners be aware of when implementing switch statements and include functions for website development?

One potential pitfall for PHP beginners when implementing switch statements is forgetting to include a break statement at the end of each case. This can cause the code to "fall through" to the next case unintentionally. Similarly, when using include functions for website development, it's important to ensure that the file path is correct to avoid errors in loading the included file.

// Example of a correct implementation of switch statement with break statements
$day = "Monday";

switch ($day) {
    case "Monday":
        echo "Today is Monday";
        break;
    case "Tuesday":
        echo "Today is Tuesday";
        break;
    default:
        echo "It's not Monday or Tuesday";
}

// Example of including a file with the correct file path
include 'path/to/file.php';
