What is the significance of using DateTime::createFromFormat() when dealing with date and time formats in PHP?

When dealing with date and time formats in PHP, different systems or sources may provide dates in varying formats. This can lead to issues when trying to parse or manipulate these dates. The DateTime::createFromFormat() function in PHP allows you to create a DateTime object from a string representation of a date, using a specified format. This helps ensure that the date is correctly interpreted and can be easily manipulated or formatted as needed.

$dateString = '2022-12-31';
$date = DateTime::createFromFormat('Y-m-d', $dateString);
echo $date->format('Y-m-d');
