What I have to do:
1. Scan a directory and find a zip file
2. unzip this file
3. redirect the user to a specific file that has been unzipped previously (step 2.)

I dont have problems when using absolute paths. But this I cannot do since I dont know whether this will be run in Windows or Linux..
It would be easier if I could use glob with an URL:

$zip_file = glob("http://".$_SERVER['SERVER_ADDR'].$directory."*.zip"); instead of
$zip_file = glob("C:\my\actual\path\tozipfile\"*.zip")

but it does not work!

allow_url_fopen is enabled
