Approach: Make sure you have XAMPP or WAMP server installed on your machine. In this article, we will be using the WAMP server.

WAMP Server is open-source software for the Microsoft Windows operating system, developed by Romain Bourdon. It is composed of an Apache web server, OpenSSL for SSL support, MySQL database and PHP programming language. Here, before going through the program, we need to create a MySQL database in our localhost server. Then, we are supposed to make an HTML table that is linked with PHP codes. PHP is used to connect with the localhost server and to fetch the data from the database table present in our localhost server by evaluating the MySQL queries. WAMP server helps to start Apache and MySQL and connect them with the PHP file.

Follow the steps given below:

1. Creating Database: First, we will create a database named ‘geeksforgeeks’. You can use your existing database or create a new one.

create database “geeksforgeeks”

2. Create Table: Create a table named ‘userdata’. The table contains four fields:

username – varchar(100)
problems – int(11)
score – int(11)
articles – int(11)

Your table structure should look like this:

the table structure of “userdata”

Or you can create a table by copying and pasting the following code into the SQL panel of your PHPMyAdmin.

CREATE TABLE IF NOT EXISTS `userdata` (
 `username` varchar(100) NOT NULL,
 `problems` int(11) NOT NULL,
 `score` int(11) NOT NULL,
 `articles` int(11) NOT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

To do this from the SQL panel refer to the following screenshot:

create a table ‘userdata” from the SQL panel

Insert records: We will now insert some records into our table. Here we are inserting 5 records. You can add multiple records.

Or copy and paste the following code into the SQL panel to insert records in the table.

INSERT INTO `userdata` 
(`username`, `problems`, `score`, `articles`) 
VALUES ('User-2', '100', '75', '30'), ('User-1', '150', '100', '30'), ('User-3', '200', '50', '10'), ('User-4', '50', '5', '2'), ('User-5', '0', '0', '1');

To do this from the SQL panel refer to the following screenshot:

Creating folder and files:

We will now create our project folder named “GeeksForGeeks“. Create an index.php file. Keep your main project folder (for example here.. GeeksForGeeks) in the “C://wamp64/www/”, if you are using WAMP or “C://xampp/htdocs/” folder if you are using the XAMPP server respectively. The folder structure should look like this:

folder structure

Now, we have a database named geeksforgeeks, and a table named userdata. Now, here is the PHP code to fetch data from the database and display it in an HTML table.

Example:

php

<?php

$user = 'root';

$password = '';

$database = 'geeksforgeeks';

$servername='localhost:3306';

$mysqli = new mysqli($servername, $user,

$password, $database);

if ($mysqli->connect_error) {

die('Connect Error (' .

$mysqli->connect_errno . ') '.

$mysqli->connect_error);

}

$sql = " SELECT * FROM userdata ORDER BY score DESC ";

$result = $mysqli->query($sql);

$mysqli->close();

?>

<table>

<tr>

<th>GFG UserHandle</th>

<th>Practice Problems</th>

<th>Coding Score</th>

<th>GFG Articles</th>

</tr>

<?php

while($rows=$result->fetch_assoc())

{

?>

<tr>

<!-- FETCHING DATA FROM EACH

ROW OF EVERY COLUMN -->

<td><?php echo $rows['username'];?></td>

<td><?php echo $rows['problems'];?></td>

<td><?php echo $rows['score'];?></td>

<td><?php echo $rows['articles'];?></td>

</tr>

<?php

}

?>

</table>

</section>

</body>

</html>

Output: Finally, you should be able to display the records in an HTML table by fetching them from the database.
