Time\Duration::fromNanoseconds — Creates a duration from a number of nanoseconds
Creates a non-negative duration of nanoseconds nanoseconds.
The value is normalized into whole seconds and nanoseconds, see the
Time\Duration::$seconds and
Time\Duration::$nanoseconds properties.
nanoseconds
The number of nanoseconds.
Must be greater than or equal to 0.
Returns a new Time\Duration object.
If nanoseconds is negative, a
ValueError is thrown.
Example #1 Time\Duration::fromNanoseconds() example
<?php
var_dump(\Time\Duration::fromNanoseconds(1_500_000_000));Il precedente esempio visualizzerà:
object(Time\Duration)#1 (3) {
["seconds"]=>
int(1)
["nanoseconds"]=>
int(500000000)
["negative"]=>
bool(false)
}
Example #2 Measuring elapsed time with hrtime()
<?php
$start = hrtime(true);
usleep(1000);
$elapsed = \Time\Duration::fromNanoseconds(hrtime(true) - $start);
var_dump($elapsed);Il precedente esempio visualizzerà qualcosa simile a:
object(Time\Duration)#1 (3) {
["seconds"]=>
int(0)
["nanoseconds"]=>
int(1062541)
["negative"]=>
bool(false)
}
