What are the best practices for handling date manipulation and conversion in PHP when dealing with non-standard date formats?

When dealing with non-standard date formats in PHP, it is important to use the DateTime class along with the DateTime::createFromFormat() method to accurately manipulate and convert dates. This allows you to specify the format of the date string you are working with and ensure proper handling of different date formats.

// Example of handling non-standard date format conversion
$dateString = '2022-15-20'; // Non-standard date format
$date = DateTime::createFromFormat('Y-d-m', $dateString); // Create DateTime object from non-standard format
$newDateFormat = $date->format('Y-m-d'); // Convert date to standard format
echo $newDateFormat; // Output: 2022-05-20
