How can the strtotime() function in PHP be utilized for date calculations and conversions?

The strtotime() function in PHP can be utilized for date calculations and conversions by accepting a date/time string and converting it into a Unix timestamp. This Unix timestamp can then be used for various date arithmetic operations or formatting into different date/time formats. 

// Example of utilizing strtotime() for date calculations and conversions

// Convert a date string into a Unix timestamp
$dateString = "2022-12-31";
$timestamp = strtotime($dateString);

// Perform date arithmetic operations
$newTimestamp = strtotime('+1 week', $timestamp);

// Format the Unix timestamp into a human-readable date/time format
$newDate = date('Y-m-d', $newTimestamp);

echo $newDate; // Output: 2023-01-07
