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; ???????} ???}
