php中怎么获取音频时长

composer require james-heinrich/getid3

<?php
require 'vendor/autoload.php';
use getID3;

$remotefilename = 'http://www.example.com/filename.mp3';
if ($fp_remote = fopen($remotefilename, 'rb')) {
    $localtempfilename = tempnam('/tmp', 'getID3');
    if ($fp_local = fopen($localtempfilename, 'wb')) {
        while ($buffer = fread($fp_remote, 8192)) {
            fwrite($fp_local, $buffer);
        }
        fclose($fp_local);
        $getID3 = new getID3;
        //获取音频信息
        $ThisFileInfo = $getID3->analyze($localtempfilename);
        //打印音频信息
        var_dump($ThisFileInfo)
        // 获取音频时长（以秒为单位）
        $duration = $ThisFileInfo['playtime_seconds'];
        unlink($localtempfilename);
    }
    fclose($fp_remote);
}
