PHP压缩

我需要压缩/ PHP中解压缩和压缩/用C解压++ 我知道gzinflate/gzdeflate，bzcompress/bzdecompress等 - 这一切都一个方法，只是用不同的包装 但我需要的任何其他方法，使用C++没有问题，但我无法访问PHP上的扩展，所以我只能使用内置的包 我可以使用已安装的库访问吗？

我可以看到你有PHP zip扩展。因此，您可以使用bzip2，它将返回输入数据的压缩版本。它不是gzip的包装，它是完全不同的压缩算法。

如：

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

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