Gettimeofday function to get time elapse from Unix Epoch time

In PHP by using gettimeofday function we can get the time elapsed between current time and Unix Epoch time.

We get an array in return.
Here is the syntax

gettimeofday();

We will try to generate output by using this. Here is the sample code

print_r(gettimeofday());

The output of above code is here

Array
(
    [sec] => 1701315008
    [usec] => 724313
    [minuteswest] => 0
    [dsttime] => 0
)

The first element [sec] gives the time in seconds elapsed between Unix Epoch time and current time.
The second element [usec] gives in microseconds.
[minuteswest] - minutes west of Greenwich
[dsttime] - type of dst correction
All these data are related to server side and not the local time of the client computer.

Getting float data

Instead of an array we can get float value like this.

echo gettimeofday(true);

The output is here.

1701315008.7243
