To glue to the OOP, it's better to use it with DateInterval::createFromDateString

<?php
$dateB
= new DateTime('2020-12-20');
$dateA = $dateB->sub(DateInterval::createFromDateString('10 days'));
?>

more detail here :
<?php
public static function createFromDateString ($time) {}
?>

You cannot replace date_sub('2000-01-20') by DateTime::sub('2000-01-20') because DateTime::sub is not static. You have to create the DateTime object first.

Example:

<?php $dateA = date_sub('2000-01-20', date_interval_create_from_date_string('10 days')); ?>

will be replace by
<?php
$dateB
= new DateTime('2000-01-20');
$dateA = $dateB->sub(date_interval_create_from_date_string('10 days'));
?>
