Cloning a delicious account

I wrote this script in order to clone one delicious account to another. It is written in PHP using the Zend Framework, which provides a useful library for the delicious API.

This script will help you copy one delicious account to another, and can also be used to copy a selection of links (eg. a particular tag) from one account to another.

It helps circumvent some of the problems with delicious: currently delicious doesn't let you change your username. Additionally the standard delicious export/import process has problems: dates aren't preserved, public/private status of bookmarks isn't preserved, tag bundles aren't preserved.

//Set up the Zend Framework
//-------------------------
/**
 * We need the path containing the Zend library to be in our include path.
 * Change '../lib' below to point to the folder where the Zend framework lives.
 * For example if this script lives in
 * var/www/vhosts/mysite.com/docs/clone_delicious.php
 * you'll want the Zend framework to live in
 * var/www/vhosts/mysite.com/lib/Zend

//--------
//Put your delicious username and password settings in here
//SOURCE DELICIOUS ACCOUNT:

//A sensible default is to delete the source posts
//If you're trying to convert thousands of bookmarks the 
//delicious service may become temporarily unavailable. If you're deleting
//the source posts (and NOT wiping the destination account) you can just 
//re-run the script and it will carry on where it left off.
$wipeDestAccount = false; //set to true to wipe dest account before starting

//Our $posts object will contain the most recent bookmark in the first element.
//However we want to create the posts in the order of last first because
//delicious lists the most recently created items first (and we want
//to preserve the order of our posts)

//filter posts by tag or url? 
//we can transfer selected tags only using something like:
//$posts = $posts->withTags(array('tag1', 'tag2'));
//$posts = $posts->withUrl('/help/');

//iterate over posts (in reverse)
for ($x = sizeof($posts) - 1; $x >= 0; $x--) {

    //echo "Title: {$post->getTitle()}<br />";
    echo "$x: {$post->getUrl()}<br />";
    //echo "Notes: {$post->getNotes()}<br />";
    //echo "Tags: " . implode(",", $post->getTags()) . "<br />";
    flush();
       
    //create a new post and save it
    //if the post already exists we won't attempt to recreate it
    $newCheck = $destDelicious->getPosts(null, null, $post->getUrl());
