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;
}
}
