PHP compression

Question

I need to compress/decompress in php and compress/decompress it in C++ I know about gzinflate/gzdeflate, bzcompress/bzdecompress and etc. - it's all one method, just with different wrappers But I need any another method, with C++ there's no problem, but I have no access to extensions on PHP, so I can use only inbuilt package Can I access using installed libraries?

I can see you have PHP zip extension. Hence you can use bzip2, which will return a compressed version of the input data. It is not a wrapper of gzip, It is entirely different compression algorithm.

Eg:

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

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

Thank you for reply Gzip is a wrapper over deflate Unfortunately I need another algorithm
