介绍
The bzip2 functions are used to transparently read and write bzip2 (.bz2)
compressed files.
需求
This module uses the functions of the bzip2
library by Julian Seward. This module requires bzip2/libbzip2
version >= 1.0.x.
安装
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.
资源类型
This extension defines one resource type: a file pointer identifying
the bz2-file to work on.
范例
This example opens a temporary file and writes a test string to
it, then prints out the contents of the file.
例子 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);
?>
