This brief tutorial will enable web application developers to harness the power of cloud computing database, Xeround, with the best PHP MVC framework in town, CodeIgniter.
Xeround is an Israeli web startup, launched back in 2005. It specializes in cloud database software technologies, operating in the PaaS domain. Xeround is primarily known for its MySQL cloud database, which it provides with a seamless frontend application. Its unique selling point is the ability to easily scale MySQL application on multiple platforms like Amazon EC2 and Rackspace. Xeround is positioned well in the MySQL cloud database market. Xeround’s basic MySQL cloud database plan is free and pretty fast.
CodeIgniter on the other hand is an Open Source PHP MVC (Model View Controller) framework used to make high end and enterprise level web applications. The framework uses a popular MVC software design pattern, popular with most of the top web developers today. The high points of using CodeIgniter as your web application framework are massive, such as highly organized code, rapid application development and plethora of in built tools.
This tutorial aims to teach you to setup up a basic CodeIgniter application in conjunction with the Xeround cloud database, powered by Oracle’s MySQL.
This tutorial will NOT teach you to use CodeIgniter, MySQL, Phpmyadmin, FTP, HTML, CSS, XAMPP or the web stack.
It rather enables you to learn the processes involved in helping you setup your next web application using CodeIgniter with a Xeround backend.
With your XAMPP already installed and configured on your computer (Windows, Mac or Linux), you active it by following these steps.
Now, lets setup CodeIgniter. The first thing you should do is visiting Ellis Lab’s CodeIgniter page by click here. When on the home page, click on the download button on the right side. Now its time to unzip.
Once the compressed file is unzipped, name it anything you like. We have named it “CodeIgniterApp”. It is important to clean the folder of any junk, by deleting the license.txt and the user guide files. You wont need those.
To enable your CodeIgniter app to work on the localhost, which is a simulation of a website on a host, you need to copy it to your htdocs.
To do this, follow the directory structure to access your htdocs folder.
Now, just drag and drop the “CodeIgniterApp” folder into htdocs. To ensure everything went fine, open up your browser and type in localhost/CodeIgniterApp. If successful, you should see this page and probably celebrate.
At this point in time, the CodeIgniter has been successfully setup. However, it doesn’t require a database to function just to load up a simple dynamic Welcome page. As the objective of our tutorial is to use CodeIgniter with Xeround, let’s take a break from the CodeIgniter side of things and create an Account on Xeround.
As mentioned before, Xeround offers cloud database services for MySQL that are highly scalable with top notch companies providing instances such as Amazon and Rackspace.
Note: This part of the tutorial will create a sample Xeround account. The username and password will not be disclosed.
a) Shared Environment
b) High Availability Guaranteed
c) Throughput: up to 1MB/s
d) Connections: up to 5
Here is a sample of what we’ve filled in for this tutorial account:
Now that we have our Xeround database setup, it is time to connect the database with CodeIgniter.
Currently, they are set to localhost but since we want Xeround, we would need to add the details in the blank spaces using the notes we took earlier. By the way, Xeround works on localhost and web!
So based on the tutorial account details, it looks like this once its filled:
$db['default']['hostname'] = instance26267.db.xeround.com:16438;
$db['default']['username'] = ‘user’;
$db['default']['password'] = ‘pass’;
$db['default']['database'] = ‘neil’;
Note: Although you do not have access to the tutorial Xeround account we created, you can still use these database instance details. However, we recommend you create your own. This is only for demonstration purposes.
Tip: In order to avoid lagging, it is better to disable persistent connections within your CodeIgniter application by editing line 57 of database.php. You simply have to set $db['default']['pconnect'] = FALSE; to false. This ensures that there are no lags, since there is a limit of 5 connections in the Xeround FREE plan.
Congratulations. You have successfully completed the essential portion of the tutorial. You have connected your Xeround Cloud Database with your CodeIgniter application. What’s next? Well, its time for some testing.
Lets create a sample table structure.
So what this does is basically creates a Controller called Tables, loads the DBForge class of CodeIgniter (used to create tables) and creates a table called Test_Table. If returns messages on the success or failure.
Now lets try adding some real world data into our table. To do that, we will create a small application that stores users’ first and last name. Since the scope of the tutorial is not to teach CodeIgniter or programming whatsoever, the files have been supplied to enable you to learn. The end result of the small application is shown below.
Oh by the way, don’t forget to turn on the following autoload.php options by going into CodeIgniterApp/application/config/autoload.php:
