winzip32.exe -a -en c:\test.zip c:\strbud.txt

This is an example of what I want to call in a php page.
I call this from cmd.

How do I do this?

I am running Apache on Win2000 server where winzip32 is in /Bin.

If you want me to scream suggest that I run this on a poxy Linux box!!!!!

Many thanks

I saw someone post something like:

<?
exec("start winzip32.exe....");
?>

if might have been system instead of exec.

Anyway, make sure you properly escape necessary characters.

Use the system command.

There are build in libraries for gzip and bzip. Would that work?

It would certainly be faster, depending on the amount of data ...

Well michael was right and also...you need a linux box 😃

[levi_501_dehaan]

Well I Definantly wont suggest that you run a Poxy Linux box...
Never would I do that...Ohh just to think of doing that makes my head spin.

here is a class to add and remove files to a gzip.

# add data to archive

# and write gzip file
$gz->write_file($path);



#step 2
# extracting content from archive
if( $g = $gz->extract($path) ){
  # print result structure
  print_r($g);
}

mann... he's a fast typer... wink
look! perfect indentation too... without tab

[levi_501_dehaan]

😃
well ya know, I gots M4D sk1||z ! 🙂

I am a fast typer too 🙂. i thought all programmers were? maybe its just my family. or maybe your just slow 😃 j/k

-=Levi=-

[michael]

heh. For use only when the built in library is unavailable. =)
Or is that a module... damn. Cannot recall.

[jeremuck]

NUHHH UHH... I type faster than you can type..

and my dad can type faster than your dad... stick out tongue

actually, my dad claims he can type at 200 wpm. I'm not sure I believe it's that fast... I type fast and I'm only like 80...
