雑にm3uのプレイリスト作るやつ。

m3u.php

<?php
  $files = glob('*.m4a');
  foreach($files as $file) {
    $duration = `exiftool -Duration '{$file}' | cut -d ':' -f 3,4`;
    $duration = explode(':', $duration);
    $extinf = (int)$duration[0]*60 + (int)$duration[1];
    $title = substr($file, 3, -4);
    $album = basename(getcwd());
    $artist = basename(dirname(getcwd(), 1));
    printf('#EXTINF:%d,%s' . PHP_EOL, $extinf, $title);
    printf('%s\%s\%s' . PHP_EOL, $artist, $album, $file);
  }
