joining several mp3 files and output as mov file with ffmpeg

I am trying to join sev开发者_运维百科eral mp3 files and output it as .mov file with ffmpeg.

Anyone knows about the command line to do that ?

Thanks

This is how I did it with the help of http://www.sourcerally.net/Scripts/20-PHP-MP3-Class

<?php
// This is the class to generate mp3 files based on the anti-spam words

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);
    }   
}
