What are potential methods for formatting dates in PHP, specifically for IPTC data?

When working with IPTC data in PHP, it is important to properly format dates to ensure consistency and compatibility with the IPTC standard. One common method for formatting dates in PHP is using the date() function along with the strtotime() function to convert dates to a desired format. Additionally, the DateTime class in PHP provides a more object-oriented approach for working with dates and times. 

// Example of formatting a date for IPTC data using the date() function
$date = "2022-10-15";
$formatted_date = date("Ymd", strtotime($date));
echo $formatted_date;

// Example of formatting a date for IPTC data using the DateTime class
$date = new DateTime("2022-10-15");
$formatted_date = $date->format("Ymd");
echo $formatted_date;
