Decompressing a string with zlib problems

Graham Anderson <grahama@xxxxxxxx> · Thu, 27 Oct 2005 16:01:19 -0700

I am having problems decompressing a zlib'd string located in a file.

In the file headers, the compression says that it is  zlib.
But, when I  'gzinflate' the string, I get the error: gzinflate():  
data error in <b
Is the below NOT a zlib or some strange variant ?

anyone know ?

$string = pack("H*", $hex);

The Output SHOULD look something like this:
