Are there any potential pitfalls to be aware of when converting dates to timestamps in PHP?

One potential pitfall when converting dates to timestamps in PHP is that the date format may not be recognized by the strtotime() function, resulting in unexpected output or errors. To avoid this issue, it is recommended to use the DateTime class to convert dates to timestamps in a more reliable and flexible way.

$date = '2022-01-01';
$timestamp = (new DateTime($date))->getTimestamp();
echo $timestamp;
