What are the potential drawbacks of using strings for date calculations in PHP?

Using strings for date calculations in PHP can lead to potential drawbacks such as difficulty in handling different date formats, timezone issues, and limited functionality for date manipulation. To solve this, it is recommended to use PHP's built-in DateTime class, which provides a more robust and reliable way to work with dates and times. 

// Create a DateTime object for the current date
$now = new DateTime();

// Perform date calculations using DateTime methods
$now->modify('+1 day');
$now->modify('-1 week');

// Format the date in a specific format
echo $now->format('Y-m-d');
