PHP is one of the most common server-side scripting languages developers worldwide use for web development. When it comes to creating a PHP chart using data contained in a database, most developers prefer the MySQL database. MySQL, an open-source RDBMS (Relational Database Management System), helps automate the process of retrieving data. Using PHP and MySQL together, developers can build just about any type of website, simple or complex. For example, you can create a pie chart in PHP and MySQL to display proportion/relative data on your website/web app.

Are you looking to create a PHP chart? While charts are a great way to make sense of raw data, the general perception is that creating a PHP chart using data from the MySQL database is a difficult and time-consuming process. But it isn’t as difficult as you think if you’re using an efficient charting library. In this article, we’ll show you how to create a pie chart in PHP MySQL and why FusionCharts is the best PHP chart tool.

Why Create A Pie Chart In PHP And MySQL?

A simple pie chart in PHP MySQL

A pie chart is essentially a circular graph, where the circle is divided into different slices or sectors. Each slice in the chart shows a proportion of the whole. You can use these charts to represent categorical data and a parts-to-whole relationship.

When it comes to creating a PHP pie chart, you can obtain the data for the chart statically by defining the data during the creation of the chart. However, the efficient way is to retrieve data dynamically from another source like MySQL. This way, your chart will always show up-to-date data. While there are several databases for PHP-based web development, MySQL is the most popular DBMS for PHP.

Here are a few reasons why most PHP developers prefer MySQL:

  • Provides an easy way to save website data
  • Helps automate the process of retrieving data
  • Create highly interactive web apps
  • Cost-effective and functional
  • Superior performance
  • Open source
  • Fast and easy maintenance
  • Compatible with almost every modern server, such as Apache and IIS

How Can I Create A Pie Chart In PHP and MySQL Using FusionCharts?

With FusionCharts, you can create a pie chart in PHP MySQL by using the data string method or data URL method.

Here, we’ll create a sample pie chart for representing “Production by Factory” using the data string method. The database contains only two tables, namely “Factory_Master” for storing the name and ID of factories and “Factory_Output” for storing the number of units produced by factories for a specific date.

Here are the main steps for creating a pie chart in PHP MySQL :

  1. First, we need to include the FusionCharts.js JavaScript class and FusionCharts.php. This will help embed charts easily.
  2. Next, include DBConn.php to connect to the database.
  3. Generate XML document and store it in a strXML variable.
  4. Render the Pie 3D Chart with data from $strXML.

Here is the sample code for creating the pie chart:

<?php
      //We've included ../Includes/FusionCharts.php and ../Includes/DBConn.php, which contains
      //functions to help us easily embed the charts and connect to a database.
      include("../Includes/FusionCharts.php");
      include("../Includes/DBConn.php");
      ?>
      <HTML>
         <HEAD>
        <TITLE>FusionCharts - Database Example</TITLE>
        http://../../FusionCharts/FusionCharts.js
     </HEAD>
     <BODY>
     <CENTER>
     <?php   
   //In this example, we show how to connect FusionCharts to a database.
   //For the sake of ease, we've used a MySQL database containing two
   //tables.
   //Connect to the DB
   $link = connectToDB();
   //$strXML will be used to store the entire XML document generated
   //Generate the chart element
     $strXML = "<chart caption='Factory Output report' subCaption='By Quantity' pieSliceDepth='30' showBorder='1' formatNumberScale='0' numberSuffix=' Units'>";
   //Fetch all factory records
     $strQuery = "select * from Factory_Master";
     $result = mysql_query($strQuery) or die(mysql_error());
   //Iterate through each factory
       if ($result) {
          while($ors = mysql_fetch_array($result)) {
          //Now create a second query to get details for this factory
           $strQuery = "select sum(Quantity) as TotOutput from Factory_Output where FactoryId=" . $ors['FactoryId'];
           $result2 = mysql_query($strQuery) or die(mysql_error()); 
           $ors2 = mysql_fetch_array($result2); 
          //Generate <set label='..' value='..'/>
           $strXML .= "<set label='" . $ors['FactoryName'] . "' value='" . $ors2['TotOutput'] . "' />";
          //free the resultset
           mysql_free_result($result2);
          }
     }
           mysql_close($link);
           //Finally, close <chart> element
           $strXML .= "</chart>";
           //Create the chart - Pie 3D Chart with data from $strXML
           echo renderChart("../../FusionCharts/Pie3D.swf", "", $strXML, "FactorySum", 600, 300, false, true);
        ?>
  </BODY>
</HTML>

The above code will render the following chart:
