如何上傳mp3文件並獲得laravel的持續時間4.2

Question

我想在Laravel上傳MP3文件，然後獲取MP3的持續時間。這裏是我的代碼，但它不工作：

$music_file = Input::file('audio_path'); 
$file_music = date('Y-m-d-H-i-s')."-".$music_file->getClientOriginalName(); 
$path = public_path('assets/music/' . $file_music); 
$path = $music_file->getRealPath(); 

Answer 1

移動MP3

$music_file = Input::file('audio_path'); 
$file_music = date('Y-m-d-H-i-s')."-".$music_file->getClientOriginalName(); 
$path = public_path('assets/music/' . $file_music); 
$music_file->move($path,$file_music);
