How to fetch data from localserver database and display on HTML table using PHP ?

06 Jun, 2022
In this article, we will see how we can display the records in an HTML table by fetching them from the MySQL database using PHP. 
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 code to establish connection with the localserver --><?php // Username is root$user = 'root';$password = ''; // Database name is geeksforgeeks$database = 'geeksforgeeks'; // Server is localhost with// port number 3306$servername='localhost:3306';$mysqli = new mysqli($servername, $user,                $password, $database); // Checking for connectionsif ($mysqli->connect_error) {    die('Connect Error (' .    $mysqli->connect_errno . ') '.    $mysqli->connect_error);} // SQL query to select data from database$sql = " SELECT * FROM userdata ORDER BY score DESC ";$result = $mysqli->query($sql);$mysqli->close();?><!-- HTML code to display data in tabular format --><!DOCTYPE html><html lang="en"> <head>    <meta charset="UTF-8">    <title>GFG User Details</title>    <!-- CSS FOR STYLING THE PAGE -->    <style>        table {            margin: 0 auto;            font-size: large;            border: 1px solid black;        }         h1 {            text-align: center;            color: #006600;            font-size: xx-large;            font-family: 'Gill Sans', 'Gill Sans MT',            ' Calibri', 'Trebuchet MS', 'sans-serif';        }         td {            background-color: #E4F5D4;            border: 1px solid black;        }         th,        td {            font-weight: bold;            border: 1px solid black;            padding: 10px;            text-align: center;        }         td {            font-weight: lighter;        }    </style></head> <body>    <section>        <h1>GeeksForGeeks</h1>        <!-- TABLE CONSTRUCTION -->        <table>            <tr>                <th>GFG UserHandle</th>                <th>Practice Problems</th>                <th>Coding Score</th>                <th>GFG Articles</th>            </tr>            <!-- PHP CODE TO FETCH DATA FROM ROWS -->            <?php                // LOOP TILL END OF DATA                while($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.
