What potential pitfalls should be avoided when using strtotime in PHP?

When using strtotime in PHP, one potential pitfall to avoid is relying on ambiguous date formats that strtotime may interpret incorrectly. To prevent this, it's best to use unambiguous date formats or provide additional context to strtotime by using date_create_from_format instead. 

$dateString = '2022-12-15';
$date = date_create_from_format('Y-m-d', $dateString);
if ($date) {
    $timestamp = $date->getTimestamp();
    echo $timestamp;
} else {
    echo "Invalid date format";
}
