介紹
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.
安裝
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.
執行時期組態
php.ini中沒有定義此延伸的組態指令。
資源類型
This extension defines one resource type: a file
pointer identifying the bz2-file to work on.
範例
This example opens a temporary file and writes a
test string to it, then prints out the contents of the
file.
範例 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
print bzread($bz, 10);
// output until end of the file (or the next 1024 char) and close it.
print bzread($bz);
bzclose($bz);
