Witam.
Potrzebuje do pliku ZIP generowanego przez php dodac pliki znajdujace sie na serwerze. Z phpMyAdmin wyciagnolem klase obslugujaca ZIPy...

Niestety potrafie jedynie zapisac do tego ZIPa pliki txt...
test.php:
<?php
require('zip.lib.php');
$zipfile = new zipfile();
// add the binary data stored in the string 'filedata'
$filedata = \"jakis text\";
$zipfile -> add_file($filedata, \"file.txt\");
// OR instead of doing that, you can write out the file to the loca disk like this
:
$filename = \"output.zip\";
$fd = fopen ($filename, \"wb\");
// then offer it to the user to download:
?>
<a href=\"output.zip\">Click here to download the new zip file.</a>
i teraz pytanie:
Czy ktos potrafilby napisac mi jak mozna dodac do ZIPa pliki pdf?? Nie koniecznie za pomoca tej klasy... jesli ktos ma jakis inny gotowy skrypt i chcialby sie podzielic chetnie zobacze
Dodawanie do ZIP'a, Jak dodac do zipa pliki z servera??
