PHP time() Function Explained: Unix Timestamp Usage

The purpose of the time() function in PHP is to retrieve the current Unix timestamp.

The Unix timestamp is a number that represents the seconds elapsed since January 1, 1970, 00:00:00 GMT. The function time() returns the current Unix timestamp, which can be used to record event times, calculate time intervals, or compare with other times.

Sample code:

$current_time = time();
echo $current_time;

The output will look something like: 1624404894

The time() function can be used for date and time manipulation, such as getting the current time, calculating time intervals, and comparing dates.
