读取音频文件时长

需要使用第三方库:getID3-master,需要使用引用两个文件夹:getid3,helperapps

private function voiceTime($img){
        //包含文件
        $path =__DIR__.'/../libs/getid3/getid3.php';
        $fileName =realpath($path);
        if (!file_exists($fileName) || !include_once($fileName)) {
            return 0;
        }
        include_once($fileName);

        try{
            $mp3_path=__DIR__.'/../../../public/'.$img;
            $getID3 = new getID3();  //实例化类
            $ThisFileInfo = $getID3->analyze($mp3_path); //分析文件，$path为音频文件的地址
            $fileDuration=$ThisFileInfo['playtime_seconds']; //这个获得的便是音频文件的时长
            $time = (int)ceil($fileDuration);
            return $time;
        }catch (Exception $e){
            return 0;
        }
    }
