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;

        }

    }
