Hi!
Ich hab folgenden Code im Netz gefunden:
Und mit folgendem Code wird ein Zip aus der Datei test.txt erstellt, die im selben Ordner ist:
Mein Problem ist jetzt mehrere Dateien zu packen. Also z.B. test1.txt und test2.txt.
Ich hab schon alles Mögliche probiert aber es haut nicht hin.
Ich hoffe ihr könnt mir helfen.
Vielen Dank schonmal,

Und mit folgendem Code wird ein Zip aus der Datei test.txt erstellt, die im selben Ordner ist:
Code:

$filename = 'test.txt';

$fp = fopen ($filename, 'r');

fclose ($fp);

// entêtes HTTP
header('Content-Type: application/x-zip');
// force le téléchargement
header('Content-Disposition: inline; filename=archive.zip');
// envoi du fichier au navigateur
echo $archive;

Mein Problem ist jetzt mehrere Dateien zu packen. Also z.B. test1.txt und test2.txt.
Ich hab schon alles Mögliche probiert aber es haut nicht hin.
Ich hoffe ihr könnt mir helfen.
