Duration

Duration’s parent is TimeSignature.

Read duration informations

use PhpTabs\PhpTabs;

$song = new PhpTabs('my-song.gp5');

// Get a time signature duration
$duration = $song->getMeasureHeader(0)
                      ->getTimeSignature()
                      ->getDenominator();

echo sprintf("
Duration
--------

index: %s
value: %s
time: %s
is dotted: %s
is double-dotted: %s

",

$duration->getIndex(),
$duration->getValue(),
$duration->getTime(),
$duration->isDotted() ? 'true' : 'false',
$duration->isDoubleDotted() ? 'true' : 'false'
);

It will ouput something like:

Duration
--------

index: 2
value: 4
time: 960
is dotted: false
is double-dotted: false
