PHP - what is diff between date_timestamp_get(date_create()) and time()?

Question

Both of those code are generate the same timestamp, so what their diff??

Does it affect the speed of processing??

echo date_timestamp_get(date_create()); // e.g. 1478854173
echo time(); // e.g. 1478854173

And does it depend on the local time of user? Or depends on the local time of server?

Answer 1

As you can see the first approach is using two function calls, while the second is done with just one call. So theoretically using just time() should be faster ... in a matter of microseconds or less.

The only benefit of the first approach is that you can pass whatever date you want to date_create() and get its timestamp like this:

date_timestamp_get(date_create('2016-12-12 12:00:00'));

while time() returns you the current timestamp.
