 Maybe I went to a wrong way of asking such question: whenever you see it
 is related to VB, just ignored...
   Anyways, anybody has experience working with zlib and PHP?  is the text
 compressed in zlib compatible with PHP gzuncompress?

   THANK YOU.

 My previous post below:

 What I am trying to do:

 - in VB, compress a string
 - save it as a file
 - use php to open it, then gzuncompress it

 I am using a vb wrapper in:

 http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=42297l
n gWId=1

 I am sure that the above program works, since it can uncompress the
 file.  Acutally this program is only an interface using the zlib

Have you tried 'compressing' something using PHP and then 'uncompressing' it 
using the VB-zlib wrapper?

 just another question, what is the difference between gzuncompress and
 gzdeflate  ??

gzuncompress() - gzcompress()
gzinflate()- gzdeflate()

There seems to be an error in the manual listing:

  gzuncompress -- Uncompress a deflated string

[PHP] zlib compatibility

2004-05-28 Thread Francis Mak
Hi,

What I am trying to do:

- in VB, compress a string
- save it as a file
- use php to open it, then gzuncompress it

I am using a vb wrapper in:

http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=42297ln
gWId=1

I am sure that the above program works, since it can uncompress the
file.  Acutally this program is only an interface using the zlib

I used the above demo, compressed a string then saved it as a file.
When I tried to use php to gzuncompress it, I got data error.  What is the
problem?  aren't they both using the zlib?

I also tried  gzinflate, still the same 'gzinflate(): data error in...'
below is the php code:

$handle = fopen(/tmp/tmpCompress.txt, r);
$contents = fread($handle, filesize(/tmp/tmpCompress.txt));
fclose($handle);
echo(gzuncompress ($contents));
I also tried to use binary read in php(i.e. rb), but still got stucked in
gzuncompress.

just another question, what is the difference between gzuncompress and
gzdeflate  ??

Thank you very much!!

Francis Mak
