I made a mistake on the title. Correction: Does not work WITHOUT bzip2

Files inside MPQ archive compressed with bzip2 algorithm.

Try to add in your php.ini:
extension=bz2.so

or add in your .htaccess:
<IfModule mod_php5.c>
  php_value extension bz2.so
</IfModule>
<IfModule mod_php4.c>
  php_value extension bz2.so
</IfModule>

or use function inside your script:
dl('bz2.so');

If nothing worked, you can't read SC2Replay files on this host.

Attach the .so file

Each operating system has it's own specific compiled version of the bz2.so.
It's not something that is part of PHP or this package...

Where can I find it for Debian?

it's a built-in module in libapache2-mod-php5

Either I am doing it wrong, or this does not work with DreamHost, and I am 
pretty sure it is the latter.

You can always do a phpinfo(); to see if it is installed.

Took me awhile to find a host that had it out of the box.  The host was 
Bluehost.

As has been said in the comments, some of the files inside the replay files are 
compressed with the bzip2 algorithm. If your host does not have the bzip2 
module installed, you will either have to find an implementation of it in pure 
php or get the host to install the module.

As this is not a problem with the parser, I am closing the issue ticket.

I'm using Dreamhost and I was able to write a quick hack to make it work, since 
Dreamhost does support command-line bzip2.  As it's a hack, I didn't bother 
making the code look good :P  Note this is EXTREMELY BAD code as it's super 
inefficient because it will create and destroy temp files a ton using up I/O 
and uses exec which is also bad form.  But... it works! And I was able to write 
it in under 2 minutes.

Modify the mpqfile.php and add an include/require to a PHP file.  I called mine 
hack.lib.  Make sure you specify the full path of course.

Search through the file and look for:

       function bzip2_decompress($string) {
                if (function_exists("bzdecompress")){
                        $tmp = bzdecompress($string);

and change it to:

       function bzip2_decompress($string) {
                if (function_exists("bzdecompresshack")){
                        $tmp = bzdecompresshack($string);

Then in your new library which you specified above, use the following code:

function bzdecompresshack($data) {
    $file = "";
    $fh = fopen("$file.bz2", w);
    fwrite($fh, $data);
    exec("/bin/bzip2 -d $file.bz2");
    $return = file_get_contents("$file");
    unlink("$file");
    return($return);
}

replace $file = "" with whatever path you want to create your temp file in.

I'm sure there is a more elegant hack out there and even ways to improve this 
(I can think of a couple myself).  But this got the job done, and I have other 
things to work on...
