PHP Compression and archive-bzip2

The BZIP2 function is used to transparently read and write bzip2 (. bz2) Compressed files.

This module uses the functions in the»BZIP2 Library of Julian Seward. This module requires BZIP2/LIBBZIP2 version >= 1.0.x.

PHP BZIP2 support is not turned on by default. Compile PHP requires--with-bz2[=dir] configuration options to activate BZIP2 support.

The following example opens a temporary file and writes a test string, and then outputs the contents of the file:

Example #1 bzip2 Small Example

<?php    $filename = "/tmp/testfile.bz2";    $str = "This is a test string.\n";    Open a file for writing    $bz = Bzopen ($filename, "w");    Write string to file    bzwrite ($BZ, $str);    Close file    bzclose ($BZ);    Open file for reading    $BZ = Bzopen ($filename, "R");    Reads 10 characters    of Echo Bzread ($BZ, ten);    Output until the end of the file (or 1024 characters later), and close.    Echo Bzread ($BZ);    Bzclose ($BZ);? >
