这是我用的http://www.sourcerally.net/Scripts/20-PHP-MP3-Class

<?php 
// This is the class to generate mp3 files based on the anti-spam words 
// Based on the PHP mp3 class at http://www.sourcerally.net/Scripts/20-PHP-MP3-Class 
// Output code based on the FPDF class at http://www.fpdf.org 
class Mp3Helper 
{ 
    function convert($fromFile, $toFile) 
    { 
     exec("ffmpeg -i $fromFile -ab 128k $toFile"); 
     unlink($fromFile); 
    } 

    function concatenate($tempFile, $phrases) 
    { 
     exec("mp3wrap " . $tempFile . " " . $phrases); 
    } 

    function fix($tempFile, $toFile) 
    { 
     exec("ffmpeg -y -i " . $tempFile . " -acodec copy " .$toFile); 
     unlink($tempFile); 
    } 
} 
?>
