PHP provides good file type detection methods using the fileinfo extension. However, that extension only detect the type of file and does not give much more information.

This package provides means to not only detect the file types of audio and video files, but also extract several types of metadata like audio and video length, resolution, etc.. It supports many types of well known video and audio formats.

    echo 'Sample rate: '.$media->getAudio()->getSampleRate().PHP_EOL;
    echo 'Channels: '.$media->getAudio()->getChannels().PHP_EOL;
  }
  // for video
  else {

    echo 'Duration: '.$media->getVideo()->getLength().PHP_EOL;
    echo 'Dimensions: '.$media->getVideo()->getWidth().'x'.$media->getVideo()->getHeight().PHP_EOL;
    echo 'Framerate: '.$media->getVideo()->getFramerate().PHP_EOL;
  }
} catch (wapmorgan\MediaFile\Exception $e) {
  // not a media or file is corrupted
