The bzip2 functions are used to transparently read and write bzip2 (.bz2)
compressed files.
This module uses the functions of the bzip2
library by Julian Seward. This module requires bzip2/libbzip2
version >= 1.0.x.
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.
This extension has no configuration directives defined in php.ini.
This extension defines one resource type: a file pointer identifying
the bz2-file to work on.
This extension has no constants defined.
This example opens a temporary file and writes a test string to
it, then prints out the contents of the file.
Example 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);
?>
