讀取音頻文件時(shí)長(zhǎng)

需要使用第三方庫:getID3-master,需要使用引用兩個(gè)文件夾: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(); //實(shí)例化類

$ThisFileInfo = $getID3->analyze($mp3_path); //分析文件，$path為音頻文件的地址

$fileDuration=$ThisFileInfo['playtime_seconds']; //這個(gè)獲得的便是音頻文件的時(shí)長(zhǎng)

$time = (int)ceil($fileDuration);

return $time;

}catch (Exception $e){

return 0;

}

}
