(PHP ActiveX) Controlling Paths of Files Added to Zip

When appending files to a .zip, it can be difficult to get the paths exactly as you want them. This example describes a way that you can control the path information when adding a single file at a time to a .zip.

<?php

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Zip')
$zip = new COM("Chilkat.Zip");

// Intialize the zip object by calling NewZip.
$success = $zip->NewZip('myZip.zip');

// Add a reference to a file on disk to the zip object.
// (When appending files to a zip, the files are not actually
// read into memory.  References to the file(s) are added.
// When WriteZip is called, the referenced files are streamed in
// and compressed to the .zip.)
$saveExtraPath = 0;
$success = $zip->AppendOneFileOrDir('/temp/a/hamlet.xml',$saveExtraPath);
// For brevity, this example will not check the return status...

// The saveExtraPath argument, if set, will cause the path information
// passed in the 1st argument to be saved in the .zip.

// To add "a/hamlet.xml", do this:
$zip->AppendFromDir = '/temp';
//  The saveExtraPath argument, if set, will cause the path information
//  passed in the 1st argument to be saved in the .zip.     But the path in AppendFromDir is
//  not added to that path saved in the .zip.     If there is a path in AppendFromDir then the
//  path in the 1st argument must be relative, not preceded by a drive or \.
$saveExtraPath = 1;
$success = $zip->AppendOneFileOrDir('a/hamlet.xml',$saveExtraPath);

// To add "temp/a/hamlet.xml", do this:
$zip->AppendFromDir = '/';
$saveExtraPath = 1;
$success = $zip->AppendOneFileOrDir('temp/a/hamlet.xml',$saveExtraPath);

// The zip written here will contain hamlet.xml three times,
// each with a different relative path.
$success = $zip->WriteZipAndClose();
