Returns the Unix timestamp representing the date.

Hatalar/İstisnalar

If the timestamp cannot be represented as int, a ValueError is thrown. Prior to PHP 8.0.0, false was returned in this case. Still, the timestamp can be retrieved as string by using DateTimeInterface::format() with the U format.

In 32-bit system the unix timestamp will overflow if the date goes beyond year 2038 and this method will return false. In 64-bit systems this function will still work as intended. For more information please see http://en.wikipedia.org/wiki/Year_2038_problem.

Note that for dates before the unix epoch getTimestamp() will return false, whereas format("U") will return a negative number.

<?php
$date
= new DateTime("1899-12-31");
// "-2209078800"
echo $date->format("U");
// false
echo $date->getTimestamp();
?>

Please note that DateTime::gettimestamp() will return an integer, but DateTime::format("U") will return a string.

timestamp must always be typed as int because in PHP, timestamps are integers.

eg:
- strftime ( string $format [, int $timestamp = time() ] ) : string
- time() // return int
- ...

So IMHO, as PHP becomes more and more a typed language, avoid using DateTime::format("U") to avoid this kind of errors "strftime() expects parameter 2 to be int, string given"
