V. Bzip2 Compression Functions

Introducere

The bzip2 functions are used to transparently read and write bzip2 (.bz2) compressed files.

Necesităţi

This module uses the functions of the bzip2 library by Julian Seward. This module requires bzip2/libbzip2 version >= 1.0.x.

Instalare

Bzip2 support in PHP is not enabled by default. You will need to use the --with-bz2[=DIR] configuration option when compiling PHP to enable bzip2 support.

Exemple

This example opens a temporary file and writes a test string to it, then prints out the contents of the file.

Exemplu 1. Small bzip2 Example


<?php

$filename = "/tmp/testfile.bz2";
$str = "This is a test string.\n";

// open 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");

// read 10 characters
echo bzread($bz, 10);

// output until end of the file (or the next 1024 char) and close it.  
echo bzread($bz);

bzclose($bz);

?>
