Need help for On the fly zip tutorial

you need to create a second array for the files and use it together with this if statement:

if (is_file($directory.$file) && !in_array($excl_files)) {

Could you give me a piece of code or something.. more exactly ?
I'm sorry but I'm new in PHP and I really need this.

just replace the old row with the new one (it's about a tiny snippet)

Please, look at my code.. what I'm wrong ?

Code:

<?php
$excl_files = array("index.php",".htaccess");

include_once("CreateZipFile.inc.php"); // zip class
class createDirZip extends createZip {
  function get_files_from_folder($directory, $put_into) {
    if ($handle = opendir($directory)) {
      while (false !== ($file = readdir($handle))) {
     if (is_file($directory.$file) && !in_array($excl_files)) {
          $fileContents = file_get_contents($directory.$file);
          $this->addFile($fileContents, $put_into.$file);
        } elseif ($file != '.' and $file != '..' and is_dir($directory.$file)) {
          $this->addDirectory($put_into.$file.'/');
          $this->get_files_from_folder($directory.$file.'/', $put_into.$file.'/');
        }
      }
    }
    closedir($handle);
  }
}


$createZip = new createDirZip;
$createZip->addDirectory('folder/');
$createZip->get_files_from_folder('folder/', 'folder/');

$fileName = 'archive.zip';
$fd = fopen ($fileName, 'wb');
$out = fwrite ($fd, $createZip->getZippedfile());
fclose ($fd);

$createZip->forceDownload($fileName);
@unlink($fileName);

?>

looks good, does it work without the filter?

Yes, perfectly.

Errors:
Warning: Wrong parameter count for in_array() in /home/test.php on line 9

Warning: Cannot modify header information - headers already sent by (output started at /home/test.php:9) in /home/CreateZipFile.inc.php on line 182

Regards,
Alex

there was an error

must be

if (is_file($directory.$file) && !in_array($file, $excl_files)) {

Now it gives me:

Warning: in_array() [function.in-array]: Wrong datatype for second argument in /home/test.php on line 9

the second value must be an array...

I solved the problem, thank you.

Alex

I'm not sure what to do with the classes file... im getting this error:
Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /home/public_html/tmp/createzip.php on line 11

Is that the right code?

and I'm calling this one:

Code:

<?php
include_once("createzip.php"); // zip class
class createDirZip extends createZip {
function get_files_from_folder($directory, $put_into) {
if ($handle = opendir($directory)) {
while (false !== ($file = readdir($handle))) {
if (is_file($directory.$file) && !in_array($excl_files)) {
$fileContents = file_get_contents($directory.$file);
$this->addFile($fileContents, $put_into.$file);
} elseif ($file != '.' and $file != '..' and is_dir($directory.$file)) {
$this->addDirectory($put_into.$file.'/');
$this->get_files_from_folder($directory.$file.'/', $put_into.$file.'/');
}
}
}
closedir($handle);
}
}


$createZip = new createDirZip;
$createZip->addDirectory('cretest/');
$createZip->get_files_from_folder('home/tyscodsu/public_html/cretest/', 'cretest/');

$fileName = 'archive.zip';
$fd = fopen ($fileName, 'wb');
$out = fwrite ($fd, $createZip->getZippedfile());
fclose ($fd);

$createZip->forceDownload($fileName);
@unlink($fileName);

?>

Ok I don't know much php but I think its this:

Code:

class createZip {
public $compressedData = array();
public $centralDirectory = array(); // central directory
public $endOfCentralDirectory = "\x50\x4b\x05\x06\x00\x00\x00\x00"; //end of Central directory record
public $oldOffset = 0;

It doesn't have a the (  ) part like this one does:

Code:

public function addDirectory($directoryName) {

you need PHP5 to run the script

you need PHP5 to run the script

oh, well that sucks... is it easy to modify to work with php 4.3.9?

oh, well that sucks... is it easy to modify to work with php 4.3.9?

you need to remove the "public , private" keywords and maybe you need to replace some php5 only functions...(better is a modern php5 enabled webserver, php4 will stop the development at the end of this year)

hello,

i need step by step instructions for this (noob) - can anyone help?

 - i downloaded the files from http://olederer.users.phpclasses.org/browse/package/2322.html. 
 - two of the files didnt have file name extensions, i am guesing they are php so i added .php to them. 

So my questions are:

Do you upload all three files (CreateZipFile.php, CreateZipFileMac.zip.php, exampleScript.php) to any location on your server?

And then what do you do?

Thank You!

EDIT:  By the way, i just have a collection of individual files that i want the user to be able to select from (checkboxes?) which would then be added to one zip file for them to download.
