PHP and FusionCharts create interactive drilling report _ PHP Tutorial

PHP and FusionCharts create interactive drilling reports. When data is analyzed, charts are directly displayed, and fake tables can interact with each other, which improves the performance. In this article, we will discuss how to use php to analyze data and use charts directly, while false tables can interact with each other, the effect will be better. This article describes how to use php with the open-source report Library FusionCharts (Project address: www.fusioncharts.com/) to create interactive drilling reports. A drilling report refers to a new report that can be opened when a user clicks the data axis in the report. This facilitates navigation between different reports.

　　What should we do?

We often need to monitor the number of visitors to our website applications and see if they have grown. in this article, we will make a small application, it shows the number of registered users on our website over a period of time.

　　Preparation:A web server that supports php. here we use apache and mysql databases to download FusionCharts.

　　Step 1. initial settings

Create an empty database fctutorial and create a subdirectory of fcdemo to store php files.

　　Step 2 initialize database data

Here we create a users Table. here there are only two simple fields: ID and user registration time:

Bytes. In this article, we will discuss how to use php to build...
