What are common challenges faced when creating a calendar with PHP and integrating it with a database?

One common challenge when creating a calendar with PHP and integrating it with a database is properly handling date and time formats to ensure consistency and accuracy. To solve this, it is important to use PHP date functions to format dates and times correctly before storing them in the database.

// Example of formatting date before storing it in the database
$date = "2022-01-15";
$formatted_date = date("Y-m-d", strtotime($date));

// Store formatted date in the database
$query = "INSERT INTO events (event_date) VALUES ('$formatted_date')";
mysqli_query($connection, $query);
