    Gets the Unix timestamp.

    Returns the Unix timestamp representing the date.

    Hatalar/İstisnalar

    If the timestamp cannot be represented as int, a DateRangeError is thrown. Prior to PHP 8.3.0, a ValueError is thrown. And, 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.

    Sürüm Bilgisi

    Sürüm: Açıklama
    8.3.0 The out-of-range exception is now DateRangeError.
    8.0.0 These functions no longer return false on failure.

    Nesne yönelimli kullanım

    <?php
    $date     = new DateTimeImmutable();
    echo     $date->getTimestamp();
    ?>

    Yordamsal kullanım

    <?php
    $date     = date_create();
    echo     date_timestamp_get($date);
    ?>

    The above examples will output something similar to:

    If you need to retrieve the timestamp with millisecond or microsecond resolution, then you can use the DateTimeInterface::format() function.

    <?php
    $date     = new DateTimeImmutable();
    $milli = (int)$date->format('Uv'); // Timestamp in milliseconds
    $micro = (int)$date->format('Uu'); // Timestamp in microseconds

    echo $milli, "\n", $micro, "\n";
    ?>

    The above examples will output something similar to:

    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"
