How can the PHP warning "strtotime() not safe to rely" be resolved?

The warning "strtotime() not safe to rely on" occurs when using the strtotime() function with ambiguous date formats. To resolve this, you can explicitly specify the date format using DateTime::createFromFormat() instead of relying on strtotime(). This ensures that the date is parsed correctly without ambiguity. 

$dateString = "2022-01-20";
$date = DateTime::createFromFormat('Y-m-d', $dateString);
echo $date->format('Y-m-d');
