Test and Deploy PHP Applications Automatically on IBM Bluemix

Continuous delivery is pretty awesome. There’s no fiddling about manually packaging or transferring code; instead, your code is automatically packaged and deployed on an ongoing basis, and you can see (and test) the results within a few minutes of making a change.

Up until recently, if you were using Bluemix, you needed to rely on external or third-party services coupled with various custom scripts to implement continuous delivery for your Bluemix applications. To make things easier, a Bluemix Continuous Delivery service was recently introduced, which comes tightly integrated with Bluemix out of the box and which provides a secure, automated way to build, test, and deploy your Bluemix applications.

I recently had an opportunity to try the new Bluemix Continuous Delivery service with a PHP application on GitHub. In my usage scenario, I wanted my target Bluemix deployment to always reflect the latest “tests passed” version of the PHP application’s dev-master branch.

The basic process I settled on was:

  • Each time a pull request is created in the GitHub source repository, the source code will be automatically tested by Travis CI with PHPUnit to ensure all unit tests pass.
  • If the unit tests pass, the pull request will be manually or automatically merged into the repository’s development branch. This merge will automatically trigger a new deployment of the application on Bluemix using a Bluemix Continuous Delivery toolchain.
  • If the unit tests fail, the pull request will not be merged and the current deployment on Bluemix will remain unaffected.

Here’s what the process looks like:

Sounds interesting? To find out how to do the same for your Bluemix applications, read my IBM developerWorks article which has a complete walkthrough of the steps.

Build a Searchable CV Database with IBM Bluemix and PHP

If you work as an independent recruiter or an in-house HR manager, you’re probably inundated with CVs from aspiring job candidates. You’re also probably collecting data from other sources: social media, LinkedIn profiles and your own interview notes. And the more data you collect, the harder it becomes to spot the right candidate for a particular requirement.

If that sounds familiar to you, relax. There are better ways of matching job candidates with business needs, especially if you let technology help you. Close your eyes and imagine an application that lets you upload all those CVs and notes, scans and indexes them, and gives you a way to search them using skill keywords like “PHP” or “aerospace engineer”.

Sounds good? I thought so too. That’s why I recently built a mobile-optimized app for CV indexing and search, which does everything I just said above.

It’s built using PHP and tightly integrated with both Searchly (for fast data indexing and search) and Bluemix Object Storage (for CV upload and download). Try out the demo on Bluemix, get the code from GitHub and read all about it in my developerWorks article.

Create and Deliver Invoices Online with IBM Bluemix and PHP

At the end of every month, I sit down for a couple of hours to create and send out invoices to my customers. Up until very recently, this involved opening up an invoice template in a word processor, entering the date and invoice number, adding up the hours worked, and calculating the total and any taxes. I’d then export each invoice as a PDF and email it out. As if that wasn’t bad enough, at the end of each accounting year, I had to review a directory full of PDF files to calculate how much I’d earned, if any invoices were unpaid, and how many projects I’d completed.

Sounds tedious? It was.

A few months ago, I decided I needed a better, less annoying approach. I decided to create a Web-based invoice generator, one that would need only the minimum necessary information from me and would take care of everything else (including generation, delivery and reporting). Since the plan was to eventually release it as an open source project for anyone to use and since every firm has its own invoice format, easy customization of the invoices was also a key design factor.

It didn’t take long to come up with a working prototype and go from there to the finished product. The final version of the application asks for basic invoice details (which customer, what was purchased, for how much) and then created a PDF invoice by merging this input with an HTML template. The template is fully customizable (so long as you know HTML, you can add your own logo, fonts, colours and layout) and the final invoice is saved online, sent to the customer via email and can be exported as a PDF file on demand. Oh, and it’s fully mobile-optimized too, so you can bill a customer with just a few keystrokes even if you’re travelling…

Here’s a sample invoice:

To make reporting and management easier, I wrapped a couple of views around the information in the database:

I used a bunch of different tools to create this application:

If you’re looking for a better way to do invoices, try the live demo or fork the code on Github and use it for your own business. If you’re interested in finding out how to deploy or customize the application, read my developerWorks article for the full details.

Build a Mobile Web App for Assisting Stray Dogs

Ever seen an injured stray on the side of the road and wished you could help, but didn’t know who to call? A couple of months ago, I started thinking about how technology could help address this problem. I began to imagine a mobile application which anyone could use to quickly report injured or ill strays to a central database, including photos and GPS locations. This information could then be used by rescue agencies dedicated to stray assistance.

The more I thought about it, the more viable it seemed. After a few experiments, I had the basic user interface ready and a MongoDB database provisioned to receive user reports (with GPS coordinates automatically included). I added an option for users to attach photos from their device cameras to their reports, and hooked it all up to the Google Maps API so that every report could be correlated with a visual map location. A few minutes later, and it was live on Bluemix.

Here’s what the reporting form looks like:
stray-report
And here’s an example report cross-referenced with Google Map data. This additional information makes it easier to locate the animal being reported.
stray-map
Try the prototype out, or fork the code on Github and use it for your own neighbourhood or city. If you’re interested in finding out more, read my developerWorks article, which walks you through all the technical details.

Create a Browser-Based PDF Storage and Search Application

Like most people, I send and receive a lot of documents over email, and the vast majority of those are in PDF format. Over the last few months, I’ve been playing with the idea of moving all these documents into a single location and building an application to automatically index them. This would not only make it easier to find a specific one quickly, but also simplify backing things ups.

Fast forward to last week, and I was reading about some of the Watson services in IBM Bluemix. It occurred to me that it would be fairly easy to combine the Watson Document Conversion service with the AlchemyAPI Keyword Extraction service to automatically turn PDFs into text and then extract keywords from them. I could store the keywords in a database and wrap a search interface around it to create a fairly neat little PDF storage/search application.

As it turned out, it worked exactly as I’d thought it would. A few hours of coding and I had the skeleton of a working application. A few more hours to hook it up with a couple of data stores (MongoDB for the keywords, a Swift object store for the actual PDFs) and add a pretty GUI, and my application was live on Bluemix.

The final version lets users select and upload PDF documents from their computer. As each document is uploaded, it is automatically and intelligently scanned for keywords and those keywords are extracted and stored in a database. Users can later search by keyword to quickly identify and download documents relevant to their needs. Needless to say, it’s all mobile-optimized, so you can get to your documents from both your smartphone and your desktop computer.

Here’s an example of what it looks like in action:

pdf-keyword-search

Build a Notepad Application with PHP, MongoDB, and IBM Bluemix

I’ve been looking for an excuse to play with MongoLab’s DBaaS for a while…so when I had to choose a database for my latest IBM Bluemix application, MongoDB was first on my list. I like the idea of a document-oriented database as an alternative to the traditional RDBMS, and I was keen to try this in a real-world context.

As it turned out, MongoDB’s document-oriented structure was a great fit for my idea of a fast, searchable, color-coded notepad in the cloud. Each “note” is modeled as a document in a MongoDB collection, and full-text searches across the documents in the collection are extremely efficient. Thanks to MongoLab’s browser-based management, it was also very easy to configure and connect the MongoDB database to the PHP application running on Bluemix.

The end result is a low-overhead mobile Web application that lets you store, categorize and search free-form text notes in the cloud. Check it out on Github, or read more in this IBM developerWorks article.

Build a PHP App that Uses GPS Data From an IoT Device

For many people, the Internet of Things is…well, the Next Big Thing. It’s all about using the cloud, real-time data, and new sensor technology to collect, store and analyze information from a wide range of previously-unwired sources: your house, your car, your refrigerator, your pet and so on.

While IoT is certainly very exciting, it’s hard to figure out exactly how to get started building IoT applications…especially if you’re a Web developer without a background in electrical engineering (like me). So I decided to invest a few weekends in learning about IoT and seeing if I could actually get a working IoT application up and running in PHP.

That’s where the Internet of Things Foundation (IoTF) service came in. A hosted cloud service that’s available through IBM Bluemix, IoTF makes it super-easy to aggregate real-time streams for devices and do something useful with them. After a little bit of research, I was able to successfully use it to retrieve GPS coordinates from my Android smartphone and then combine that data with the Google Maps API (and a little bit of PHP glue) to plot my phone’s location on a map in real time.

php-iotIt’s a simple application, but it goes a long way towards demonstrating the potential of IoT applications…and it’s also given me the foundation I need to begin building more complex applications. If this sounds like something you’d like to get in on as well, take a look at my IBM developerWorks article about using IoT with PHP, and also has some code for you to get started with.

Build and Deploy an Investment Tracking Application in the Cloud with IBM Bluemix

Financial data is now more accessible than ever via open APIs. This makes it easy to build Web or mobile applications that let you track your investment portfolio on a minute-by-minute basis (or at least as often as you care to check it). That’s the idea behind my new portfolio tracking application, which lets you create a virtual portfolio of stocks and then shows you the current market value at any given point.

How does it work? It’s mainly driven off the Quandl API, which is free to use and offers access to both open and premium financial databases. The Quandl API supports thousands of datasets, but I’m only using the free WIKI dataset, which is a community-curated list of end-of-day stock prices and dividends for 3,000 US companies.

The application itself is written in PHP using the Silex micro-framework and uses a hosted Cloudant instance for data storage. jQuery Mobile ensures that the interface works well on smartphones, and the entire thing is hosted on Bluemix for maximum scalability. There’s also a little bit of HybridAuth in the mix, just so that every user can create his or her own account in the system using existing Google credentials.

Sounds interesting? Try a demo, check out the source code on Github, or read about how I developed it in this two-part IBM developerWorks article.
