A particular topic or data trend is depicted using a line chart data representation. Most of Google’s products, such as Google Trends and Google Analytics, employ the line graph data format. Making a line chart in PHP and MySQL helps the user see how the data progresses. The line graphs illustrate where there are high peaks and whether the trend is upward or decreasing.
The most widely used programming language for web development is PHP. It’s open-source, accessible, and server-side (the code is executed on the server). MySQL is a Structured Query Language (SQL)-based Relational Database Management System (RDBMS). It’s also open-source and free. The combination of PHP and MySQL opens up a world of possibilities for building websites, ranging from modest contact forms to massive corporate portals, by making a PHP chart, for example.
This post aims to show you how to make line charts with PHP and MySQL with data from a database using FusionCharts.

What Is the Use of a Line Chart? Can we make one in PHP?
The primary purpose of a line graph is to track changes over time, both short and long. It’s also used to compare changes in various groups during the same period. When there are modest changes, it is always best to use a line graph rather than a bar graph. For example, a company’s finance department could want to chart the changes in the quantity of cash on hand over time. They depict the points on the horizontal and vertical axes using a line graph in such a situation. It generally denotes the data’s time period. Line graphs are valuable because they display data variables and patterns, and they can aid in making predictions about the outcomes of data that has not yet been recorded. They can also show the relationship between many dependent variables and one independent variable. However, line graphs are only effective for comparing data sets if the axes have the same scales. According to some experts, a single chart should have no more than four lines; any more than that makes it challenging to comprehend.How Can We Create a Line Chart in PHP and MySQL?
The chart may be obtained in four stages. First, writing server-side PHP code to fetch data from a MySQL database is required to bind the data and make a chart.Do You Have LAMP or WAMP Installed?
If you have the software installed already, you can skip this step. If not, we need to install MySQL, Apache web server, and PHP to get the codes in this article to execute. This stack is commonly referred to as the *AMP(Apache MySQL PHP) stack, and depends on the platform on which it runs. It is referred to as WAMP (Windows Apache MySql PHP) or LAMP (Linux Apache MySql PHP) (Linux Apache MySQL PHP). As a result, several vendors have packaged this stack and made it accessible for download. We’ll be using Bitnami’s WAMP package for this tutorial. You will be requested to open the app at the end of the WAMP package installation. The Administer Servers tab allows you to manage the MySQL DB server and the Apache server.How to Create a Database and Initialize With Data in MySQL?
The WAMP package, which was installed previously, provides a browser-based application for interacting with the MySQL database. Let’s look at how to build a table and seed data. The data is organized in a table with two columns: the player’s name and the number of wickets. The following is the SQL command to create the table:USE test;
CREATE TABLE top_odi_wicket_takers(
player varchar(255),
wickets integer,
PRIMARY KEY (player)
);
To seed the table we use initial data. This is shown below:
INSERT INTO top_odi_wicket_takers(player, wickets) VALUES('MA Starc', 34);
INSERT INTO top_odi_wicket_takers(player, wickets) VALUES('ST Finn', 27);
INSERT INTO top_odi_wicket_takers(player, wickets) VALUES('Imran Tahir', 25);
INSERT INTO top_odi_wicket_takers(player, wickets) VALUES('M Morkel', 21);
INSERT INTO top_odi_wicket_takers(player, wickets) VALUES('TA Boult', 36);
INSERT INTO top_odi_wicket_takers(player, wickets) VALUES('TG Southee', 28);
INSERT INTO top_odi_wicket_takers(player, wickets) VALUES('CJ Anderson', 25);
INSERT INTO top_odi_wicket_takers(player, wickets) VALUES('Wahab Riaz', 25);
INSERT INTO top_odi_wicket_takers(player, wickets) VALUES('JH Davey', 21);
INSERT INTO top_odi_wicket_takers(player, wickets) VALUES('UT Yadav', 22);
The SELECT SQL command can verify whether the data has been inserted.
