PHP gets the current timestamp, and php gets the current time

PHP provides a special function to obtain the current timestamp, that is, the time () function.
The time () function obtains the current UNIX timestamp. The returned value is the number of seconds from the timestamp epoch (January 1, January 1, 1970 00:00:00 GMT) to the current timestamp.
Syntax: int time (void)
The time () function does not have a parameter. The return value is the integer of the UNIX timestamp.
For example, use the time () function to obtain the timestamp of the current time. The Code is as follows.

<? Php
Echo time (); // current Timestamp
?>
