PHP圧縮

Question

メソッドはC++で問題ありませんが、PHPの拡張機能にアクセスすることはできませんので、組み込みパッケージのみを使用できます インストールされたライブラリを使用してアクセスできますか？

インストール済みの拡張機能：

[0] => Core [1] => date [2] => ereg [3] => libxml [4] => openssl [5] => pcre 
[6] => zlib [7] => bz2 [8] => calendar [9] => ctype [10] => curl [11] => hash 
[12] => fileinfo [13] => filter [14] => gettext [15] => gmp [16] => SPL

私はあなたがPHP zip拡張子を持つ見ることができます。したがって、bzip2を使用すると、入力データの圧縮バージョンが返されます。これはgzipのラッパーではなく、全く異なる圧縮アルゴリズムです。

例：

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

    $bz = bzopen($filename, "w"); 
    bzwrite($bz, $str); 
    bzclose($bz); 
?>
