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;

}

}
