Tiny PHP library to deal with (SMPTE) timecode through Timecode object representation.
composer require m6web/timecode<?php
require __DIR__.'/vendor/autoload.php';
use M6Web\Component\Timecode\Timecode;
// Let's say we want to create a timecode corresponding to 9hours, 2minutes, 0seconds and 3frames with a framerate of 25 (which is the default framerate btw)
// We could either create it like any other PHP objects
$timecode = new Timecode(9, 2, 0, 3, 25); // hours, minutes, seconds, frames, framerate
// Or simply using its string representation
$timecode = Timecode::createFromString('09:02:00:03', 25);
// Or even using its total number of frames
$timecode = Timecode::createFromNumberOfFrames(813003, 25);
// Now let's say we want to subtract 5hours from our timecode
$resultTimecode = $timecode->sub(new Timecode(5, 0, 0, 0));
$resultTimecode->getHours(); // 4
$resultTimecode->getMinutes(); // 2
$resultTimecode->getSeconds(); // 0
$resultTimecode->getFrames(); // 3
echo $resultTimecode; // '04:02:00:03'
