ZipLib2 Documentation

Introduction: ZipLib2 is a wrapper of original ziplib file developed by Eric Mueller.  Original ZipLib compress the data if 

you submit the data as stream. This creates an enormous hassle and you have to care a lot of things like file opening, 

reading it and then passing the content as an array. ZipLib2 wraps that method so that you can add any number of zip files 

but just supplying their absolute or relative path.  So there is no more hassle. Just supply the file name and get your zip 

file ready. By this time, ziplib can only create zip files. There is no support for reading and extracting zip files. Very 

soon we will add that support. 

------------------------------------------------------------------------------------------------------------

How to create zip file using ZipLib2:  Creating zip files using zip file is a matter of minute. Lets see how you can compress 

with ZipLib2.

ZipLIb2 exposes two methods for developers to compress files. And to output that The method for compression is “addFiles” 

which takes variable number of arguments (filenames) and then zip it. 

------------------------------------------------------------------------------------------------------------
Function addFiles($files)

$files is an array which contains name of the files to compress, as an array. You can write $files as follows

$files = array(“readme.pdf”, “news/news1.pdf”, “../mypic.jpg”);

you can supply file names with absolute path or relative path. 

That’s it, you have compressed these files. Now output your zip file. 

------------------------------------------------------------------------------------------------------------
Function Output($filename)

To output your newly created zip files just supply the name of zip file. This could also be filename with relative path and 

absolute path. Like this

$ziplib2->output(“news/archivednews.zip”);  

this time an zip file named archivednews.zip will be created in “news” folder in the same directory. But you have to take 

care of file permission. You must set the write permission of the folder where you want to put your zip file. In this example 

“news” folder must have write permission (at least 744)

-------------------------------------------------------------------------------------------------------
so guys, look at this complete example  to make the zip file. 

<?
include("zip.lib.php");
$ziper = new zipfile();
$ziper->addFiles(array("m.pdf","file.png"));
$ziper->output("zip2.zip");
?>
