Hi!

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

Code:

<?php
    // appel de la classe
    require_once('zip.lib.php');
    // nom du fichier à ajouter dans l'archive
    $filename = 'test.txt';
    
    // contenu du fichier
    $fp = fopen ($filename, 'r');
    $content = fread($fp, filesize($filename));
    fclose ($fp);
    
    // création d'un objet 'zipfile'
    $zip = new zipfile();
    // ajout du fichier dans cet objet
    $zip->addfile($content, $filename);
	
    // production de l'archive' Zip
    $archive = $zip->file();

    // 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.
Vielen Dank schonmal,
kuhlmaehn

so:

PHP:

<?
ob_start();
require('zip.lib.php');

$zipfile = new zipfile('test.zip');

$zipfile->addFileAndRead('test1.txt');  
$zipfile->addFileAndRead('test2.txt');
$zipfile->addFileAndRead('test3.txt');
$zipfile->addFileAndRead('test4.txt');
  
echo $zipfile->file();

Super vielen Dank!
Hatte schon fast aufgegeben

Ich weiss ist schon sehr alt der Beitrag,
aber wie kann ich es verhindern das das Pfad im zip mit gespeichert wird ?
