you have still this error

Parse error: syntax error, unexpected '.' in /home/ajayvibh/public_html/0-make-zip.php on line 11

no you have to change the code since WP has replaced all single quotes

Hi Olaf,

Please note that I am not using any word press (WP) at all .I am just trying to use your script on a regular website which is made manually .What I want to do take the backup of the folder using your scripts

I hope that you are getting me now. Also it is not clear whether there is need for any third party programe or some other php component /classes to use your " zip on the fly tutorial"

Any help will be help to many people indeed in using it different way.You already made such a wonderful scripts but it needs little bit more for the wise spread use.

Thanks & Regards,
Ajay Jain

I never said that you're using WP
You need to replace the single quotes from my blog because wordpress replace regular single quotes with something else. If you use that code it will not work.

you need the class from here (my code is just an extension)
http://olederer.users.phpclasses.org/browse/package/2322.html

I have downloaded the classed, changed the code, allocate full directory permission in tmp folder also also replay . & .. with some dummy name also but still it does not work.

post the code from the file here (the file with all the errors)

<?php

include_once("createZip.inc.php");

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)) {
          $fileContents = file_get_contents($directory.$file);
          $this->addFile($fileContents, $put_into.$file);
        } elseif ($file != ?ajay? and $file != ?vibha? and is_dir($directory.$file)) {
          $this->addDirectory($put_into.$file.?/?);
          $this->get_files_from_folder($directory.$file.?/?, $put_into.$file.?/?);
        }
      }
    }
    closedir($handle);
  }
}

$createZip = new createDirZip;
$createZip->addDirectory(?public_html/?);
$createZip->get_files_from_folder(?public_html?, ?public_html/?);

$fileName = ?tmp/ajay.zip?;
$fd = fopen ($fileName, ?wb?);
$out = fwrite ($fd, $createZip->getZippedfile());
fclose ($fd);

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

?>

replace the single quotes as I told before:

like
$createZip->addDirectory(?public_html/?);

must be

$createZip->addDirectory('public_html/');

you need to do that for the whole snipped

Thanks for the tips.

Yes it has worked now, thanks a lot indeed I appreciate your help.

Two small queries :

1) Is it possible to skip some folder ? Because while making the directory zip there are some system / scripts folder which are to be skipped.

2) Is it necessary to have php5 support on the server ? Can it work on the php4 supported server

Q1:
yes you can create an array and test each value like:

class createDirZip extends createZip {

public $exclude = array();

public function get_files_from_folder($directory, $put_into) {

if ($handle = opendir($directory)) {

while (false !== ($file = readdir($handle))) {

if (is_file($directory.$file)) { 

$fileContents = file_get_contents($directory.$file);  

$this->addFile($fileContents, $put_into.$file); 

} elseif ($file != '.' and $file != '..' and is_dir($directory.$file) and !in_array($this->exclude)) {

$this->addDirectory($put_into.$file.'/');

$this->get_files_from_folder($directory.$file.'/', $put_into.$file.'/');

}

}

}

closedir($handle);

}
}

$createZip = new createDirZip;  
$createZip->exclude = array('some_dir', 'next_dir');
?>

Q2:
yes you can just remove the keywords public, private ... from the methods and vars

just found here some error:

} elseif ($file != '.' and $file != '..' and is_dir($directory.$file) and !in_array($this->exclude)) {

must be

} elseif ($file != '.' and $file != '..' and is_dir($directory.$file) and !in_array($file, $this->exclude)) {

=>Yes it is working now olaf, very good work indeed.Everything I have kept at http://www.ajayvibha.com/olaf/test.php

=> In the same way is it possible to exclude some set of files also e.g exlide all the files php files (*.php) OR some specific files like ( xyz.php) etc.This will make this application quite flexible

=> I have made an online unzip file which is doing fine on local pc but on a php5 & php5 server it is not working.

All the details are at http://www.ajayvibha.com/olaf/test.php.

Following is the code of the unzip file :-

<?PHP
// create object
$zip = new ZipArchive();   

// open archive
if ($zip->open('sample.zip') !== TRUE) {
    die ("Could not open archive");
}

// extract contents to destination directory
$zip->extractTo('./');

// close archive
// print success message
$zip->close();   
echo "Archive extracted to directory";
?>

Whenever you find time just try it out.This will also to complete the application for php4 & php5 supported servers.

I would say that you need to give some permissions to the target directory

check this thread...

Could you be more specific please ?
For example on
__
$createZip->exclude = array("somefolder1", "somefolder2");

I tried to replace folder with files like
__
$createZip->exclude = array("index.php", "somefile.php");

but doesn't work.

PS. I'm new in PHP.

Alex
