What are the advantages of using DateTime::add method over strtotime function for date manipulation in PHP?

When manipulating dates in PHP, using the DateTime::add method is preferred over the strtotime function because DateTime::add provides a more object-oriented approach to date manipulation. It allows for more precise control over date calculations and avoids potential pitfalls associated with strtotime, such as ambiguity in date formats and reliance on global settings. 

// Using DateTime::add method for date manipulation
$date = new DateTime('2022-01-01');
$date->add(new DateInterval('P1D')); // Add 1 day
echo $date->format('Y-m-d'); // Output: 2022-01-02
