RackSpace Cloud Server Client Library for PHP

·

We, the developers at Leevio are currently developing an open source group collaboration application. We are using RackSpace Cloud servers since the very beginning of the development and we will also deploy in on rack space cloud.

As a part of our study we’d found that RackSpace provides excellent API to manage your cloud services. Unfortunately there are no language binding library released yet (for Cloud Server). But they’ve mentioned that they are developing one for python.

So we have spend our time for last two days and developed a PHP client library to use RackSpace cloud server API from inside a PHP application.

This client library is released under New BSD license. And is available to download/svn-checkout from it’s project page at http://code.google.com/p/phprackcloud/

There is plenty of documentation and example included. The code is mostly self explanatory. Please dont forget to check the Wiki page to get some idea on how to use this library and how far you can go. We have covered all available methods by RackSpace cloud server in our client library.

Happy clouding.

Using iPaper API to convert office documents to flash movie on the fly :)

·

Embedding documents in web applications is a challenging work. Because you need to convert these documents into flash movie and only then you can embed them in your web applications. There are many converters available out their for use. Some of them are proprietary, Some of them comes for free. There are command line tools as well as web services also to perform these conversions and make your life easier. In this post I am going to introduce you to IPaper, an excellent service from Scribd. Using IPaper API you can upload and convert your documents to flash movie on the fly, and then you can embed them using Scribd’s excellent document viewer. Scribd offers a collection of client libraries and fortunately, we have a PHP lib in that collection.

Scribd API can convert numbers of document types including the followings

* Adobe PDF (.pdf)
* Adobe PostScript (.ps)
* Microsoft Word (.doc, .docx)
* Microsoft PowerPoint (.ppt, .pps, .pptx)
* Microsoft Excel (.xls, xlsx)
* OpenOffice Text Document (.odt, .sxw)
* OpenOffice Presentation Document (.odp, .sxi)
* OpenOffice Spreadsheet (.ods, .sxc)
* All OpenDocument formats
* Plain text (.txt)
* Rich text format (.rtf)

To use IPaper API, you need to create a developer account in ScribD and get your API key and secret key. Also, download the PHP client library from http://www.scribd.com/developers/libraries

You are ready to go once you get your Scribd api key and secret key. You can upload different types of files to scribd server and of course you can make them private or publicly accessible. After successful upload and conversion you will receive a doc_id and access_key from Scribd web service. Using those data you can embed your document in your web app. Lets have a look. In the following code examples, you may find the getEmbedUrl() and getEmbedCode() functions handy. You can also use SWFObject for quick embedding 🙂

[sourcecode lang=”php”]
<?php
include_once("scribd.php");

$UpdloadData = createIPaper("gpl.pdf","pdf","public");
$EmbedUrl = getEmbedUrl($UpdloadData);
echo $EmbedUrl;
$EmbedCode = getEmbedCode($UpdloadData);
echo $EmbedCode;

function createIPaper($File, $FileType, $Access="private")
{
$scribd_api_key = "<your API key>";
$scribd_secret = "<your Secret key>";

if (empty($FileType))
throw new Exception("Filetype cannot be empty");
$Scribd = new Scribd($scribd_api_key,$scribd_secret);

$UploadData = $Scribd->upload($File,$FileType,$Access,1);
return $UploadData;
}

function getEmbedUrl($UploadData)
{
if($UploadData){
$EmbedUrl = "http://d1.scribdassets.com/ScribdViewer.swf?document_id={$UploadData[‘doc_id’]}&access_key={$UploadData[‘access_key’]}&page=1&version=1&viewMode=list";
return $EmbedUrl;
}
}

function getEmbedCode($UploadData, $Width=450, $Height=500)
{
$EmbedCode = <<<EOD

EOD;
return $EmbedCode;
}
?>

and here is how it will look after embedding

By the way, IPaper PHP client library has some cool methods like uploadFromUrl() – Check them out )

Stay in touch, In next post I will show you how to use some other exciting tools which you can use and host in your own server :). that will be fun to host your own service like this 🙂

Thanks to Rana for helping me out with iPaper.
