How to get a unix timestamp from DateTime object with PHP 5.2?

Question

I'm working on a few years old codebase and it uses DateTime. The server is using PHP 5.2.

I see that DateTime::getTimestamp() has been added after PHP 5.3.

Is it possible to get a timestamp from DateTime in PHP 5.2?

I used get_class_methods to see if the method is available, but it's not.

Array
(
    [0] => __construct
    [1] => format
    [2] => modify
    [3] => getTimezone
    [4] => setTimezone
    [5] => getOffset
    [6] => setTime
    [7] => setDate
    [8] => setISODate
)

$datetime = new DateTime();
echo $datetime->format('U');

See it in action

As of PHP 5.4 you can make this a one-liner:

echo (new DateTime())->format('U');

I hate it, that it's not possible with one line of code. Something like this `(new DateTime())->format('U')`, grrr... – algorhythm May 07 '14 at 10:19

@algorhythm You can do that in PHP 5.4+ – John Conde May 07 '14 at 11:39

Using U as the parameter to DateTime::format() is an alternative when using PHP 5.2.

$ts = $datetimeObj->format('U');

If you would take a look at the manual:

Using U as the parameter to DateTime::format() is an alternative when using PHP 5.2.

So DateTime::format('U') it is.
