What are common pitfalls when querying a MySQL database in PHP for generating a vacation calendar?

One common pitfall when querying a MySQL database in PHP for generating a vacation calendar is not properly handling date formats. Make sure to use the DATE_FORMAT function in your SQL query to format dates in the desired way. Additionally, be mindful of time zones to ensure accurate date and time representations.

// Query to retrieve vacation dates from MySQL database
$query = "SELECT DATE_FORMAT(vacation_date, '%Y-%m-%d') AS formatted_date FROM vacations";
$result = mysqli_query($connection, $query);

// Loop through results and display formatted dates
while ($row = mysqli_fetch_assoc($result)) {
    echo $row['formatted_date'] . "<br>";
}
