通过PHP在Linux上使用mp3进行wav

I want your advice on how to convert mp3 files to wav on linux via a PHP script.

I was successful with lame but only on windows, I putted lame.exe and lame.xxx.dll together and executed the PHP script posted here:

• Generating MP3 waveforms with PHP (by Andrew; 29 April 2010)

But so far so good, I'm not successful in doing the same thing on Linux.

sorry, but afaik php is only gonna let you mess with id3 tags. you're gonna want to use an external tool to get this done.

use lame:

exec("lame –decode input.mp3 output.wav");

or use mpg123:

exec("mpg123 -w output.wav input.mp3");

I am using mpg123 to convert *.mp3 files into *.wav.

// To install mpg123 {Ubuntu 12.04} sudo apt-get install mpg321

// My PHP Script (Sample)

<?php

# glob() :  to collect all files in a folder
# foreach() : to loop

foreach (glob("*.mp3") as $file)
{
    $act_name = explode ('.', $file);

    $command = "mpg123 -w {$act_name[0]}.wav $file";
    echo $command . "
";
    exec($command)  
    echo "file converted {$file}
";

    sleep(1);
}
