// or

// --------------------------------------------------
// Reading information and data in the opened archive
// --------------------------------------------------
 
// check if a file is existing in the archive, the name must precise subfolders if any
$ok = $zip->FileExists(&#39;subfolder/help.html&#39;);
 
// count the files stored in the archive
$file_nbr = count($zip->CdFileLst);
 
// retrieve the content of an compressed file in the archive

// -----------------------------
// Modifying data in the archive

// add a file in the archive
$zip->FileAdd(&#39;newfile.txt&#39;, $data, TBSZIP_STRING); // add the file by giving the content
$zip->FileAdd(&#39;newpic1.png&#39;, &#39;./images/localpic1.png&#39;, TBSZIP_FILE);        // add the file by copying a local file
$zip->FileAdd(&#39;newpic2.png&#39;, &#39;./images/localpic2.png&#39;, TBSZIP_FILE, false); // add the uncompressed file by copying a local file
 
// delete an existing file in the archive
$zip->FileReplace(&#39;newfile.txt&#39;, $data, TBSZIP_STRING); // replace the file by giving the content
$zip->FileReplace(&#39;newpic1.png&#39;, &#39;./images/localpic1.png&#39;, TBSZIP_FILE);        // replace the file by copying a local file

// cancel the last modification on the file (add/replace/delete)

// ----------------------
// Applying modifications
// ----------------------
 
$zip->Flush(TBSZIP_FILE, &#39;./save/new_archive.zip&#39;); // apply modifications as a new local file
 
// apply modifications as an HTTP downloaded file

// apply modifications as a downloaded file with your customized HTTP headers
header("Content-type: application/force-download");
header("Content-Disposition: attachment; filename=download.zip");
header("Expires: Fri, 01 Jan 2010 05:00:00 GMT");
$zip->Flush(TBSZIP_DOWNLOAD+TBSZIP_NOHEADER);
 
 
// -----------------
// Close the archive
// -----------------
 
$zip->Close(); // stop to work with the opened archive. Modifications are not applied to the opened archive, use Flush() to commit
