Reporting section is always a part of any system, sometimes it plays a crucial part. We have learnt this through hundreds of projects we did for our customers. So what is KoolReport and why you should consider having it in your great php application.
What is KoolReport?
By definition, KoolReport is an intuitive and flexible open-source PHP Reporting Framework for faster and easier data report delivery. Just like any php framework like Laravel or CodeIgniter, KoolReport provides developers a frame to code, a list of ready-made functionalities to build things. While other frameworks focus on constructing web applications, KoolReport only focuses on one thing: using PHP to construct great data reports.
Koolreport was born from the fact that data reports appear very often in almost all web applications. It is understandable because we always need to know the status of applications such as number of visitors, number of registered users or number of item sales and so on. We have built several hundred applications for our customers and 90% have report sections. In some of them, the report section is actually the main part. This is the biggest motivation for us to construct KoolReport in the first place.
There are 5 reasons that you would like to have KoolReport in your projects:
Easy to install and easy to use. You can install KoolReport by either downloading a copy and putting it inside your application or by using composer with a single command line. The structure of a report is very simple, one php class for report’s definition and one view file for report’s visualization. That’s why you can start using KoolReport in almost no-time.
KoolReport only does one thing and only one thing: building a good data report. Nothing more. You will not see routing, authentication or whatsoever. Is it bad? It depends on each opinion but for us, doing one thing best is better. “Make a good report” is not a simple task in fact. It includes 3 things.
First is the ability to connect to various sources and bring in data in one place. A report could be combined results from different data sources, a little from MySQL, some in Postgresql and other from CSV.
Second is the power of data processing. Data is gathered but how to fastly combine and transform them into meaningful information is the question. KoolReport contains over 30 built-in data processes which you can use with your data.
Last is data visualization capability. We have all meaningful data but without a good representation, the story could not be told. KoolReport is integrated with rich charts and graphs that come from well known libraries such as Google Chart, D3 or ChartJs for you to convey your data in the most impressive and interactive way.
Work with different environments
KoolReport can be integrated into Laravel or CodeIgniter or any MVC frameworks out and utilize their functionalities not existing in KoolReport. So KoolReport wants to be part of ecosystems, does one good thing and corporate with others, all heading to a final purpose: A great application.
Inherit experience of data report maker
Our deep experience of making data reports has been put into KoolReport. Moreover, the comments, recommendations and error report from users helps us to perfect KoolReport through many years. So using KoolReport, you are using a proven framework made by experts and growing from real use cases.
Free and open-source
Cost is always a part of the decision as always. KoolReport is released as a free and open-source library under MIT license which virtually gives you full right to use, to access and modify source-code as your own need.
So above are the top 5 reasons that you should use KoolReport inside your project. Of course, any solution has drawbacks and KoolReport will not be an exception. The reasons we give could be biased and the best way is your own experience with the framework.

We are happy to announce that we have released KoolReport core version 4.5.1 with new features. The KoolReport Pro also reaches same version number 4.5.1 with the new core update and the upgrade of individual packages such as Excel, Inputs, D3, ChartJs.
KoolReport's class is provided with new
getXml() method to get the representation of your report in
xml format. The xml contains both data and meta data of all report's datastores.
In this version, we continue to enrich methods of datastore. DataStore has a new method called
distinct(). As the name suggested, distinct method will have you to get a list of unrepeated values from a column. Furthermore, Datastore is provided with new
toJson() methods to get array and JSON. This could be useful if you need result in array form for further processing or JSON format to be returned in your REST API.
We have added new DataSource called
ExistedPdoDataSource to handle source in case you only have the PDO object but connection settings. So you only need to send your existed PDO object as parameter to your report and provide it with
JsonSpread is a new processed added to KoolReport in order to spread JSON data into column in data stream. By doing so, we are able to apply other KoolReport's processes to further process the JSON data.
Support CI/CD process
Since the popularity of CI/CD process, KoolReport library now fully support this new type of software integration and delivery processes. We understand the 1 hour token availability causes trouble for the automation delivery so we have increases the life time of token to maximum. In particular, the token will last until your subscription of KoolReport Pro is ended. If you have purchase the Perpetual Usage, the token expiration will be set the
2100-01-01 which is virtually life-time or never expired.
Support load balancing
If you are using load balancing with multiple servers containing app (with KoolReport integrated), the generated resource folders now have same name in all servers. So virtually, the client-side will be able to receive resource files regardless of servers it connects to.
D3Chart Client Events
D3 chart has been upgraded with one of the most crucial features: client events. This is the missing part in
D3 first version. Now all charts support
itemSelect event which help you to track the click of user to item on the charts. Now D3 is able to work with DrillDown package to provide interactive drill down report.
DrillDown supports D3
Missing client events hindered the collaboration of DrillDown package with D3 chart. But not anymore, since the
D3 package has supported the client events, the
DrillDown package also support generate D3 Chart. By specifying the D3 chart as drilldown widgets, the DrillDown will bind itself to D3
itemSelect to provide interactive report.
We have fixed the PieChart display in Microsoft Excel and a minor bugs happened when data is missing.
We have upgraded the core of ChartJS to latest version of 2.9.x. With this new upgrade, some of known issues has been addressed. Furthermore, we have provided new
plugins property which allows you to use most popular plugins for ChartJS like
