bz2 filter implementation backport for PHP 5.0
bzip2 compress/decompress stream filter implementation. Performs inline compression/decompression using the bzip2 algorythm on any PHP I/O stream. The data produced by this filter, while compatable with the payload portion of a bz2 file, does not include headers or tailers for full bz2 file compatability. To achieve this format, use the compress.bzip2:// fopen wrapper built directly into PHP.
