What are some recommended error handling practices in PHP, especially when dealing with date calculations and outputting data to HTML?

When dealing with date calculations and outputting data to HTML in PHP, it is important to implement proper error handling practices to ensure the code runs smoothly and does not break unexpectedly. One recommended practice is to use try-catch blocks to catch any potential exceptions that may arise during date calculations or data output. Additionally, validating input data before processing it can help prevent errors. 

try {
    // Perform date calculations
    $date1 = new DateTime('2022-01-01');
    $date2 = new DateTime('2022-01-15');
    $interval = $date1->diff($date2);
    
    // Output data to HTML
    echo "<p>Number of days between dates: " . $interval->days . "</p>";
} catch (Exception $e) {
    // Handle any exceptions that occur
    echo "An error occurred: " . $e->getMessage();
}
