PHP program to fetch data from localhost server database using XAMPP

In this article, we will see how we can display the records by fetching them from the MySQL database using PHP. 

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

XAMPP is a free and open-source cross-platform web server solution stack package developed by Apache which allows a web application to be easily tested on a local web server. Here, we can manually create a relational database and store data in tabular form by going to this link. But to operate on localhost or for storing data first we have to start Apache and MySQL from the XAMPP control panel. Let, for example, the database name is server, the table name is user_info having column name as ID, First Name, Username and Password and we have to fetch the data stored there. So, below is the PHP program whose task is to fetch data. 

Follow the steps to fetch data from the Database using PHP:

1. Create Database: Create a database using PHPMyAdmin, the database is named “geeksforgeeks” here. You can give any name to your database. 

create database “geeksforgeeks”

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

• id – int(11) – primary key – auto increment
• first_name – varchar(100)
• last_name – varchar(100)
• gfg_username – varchar(100)

Your table structure should look like this:

the table structure of “user_info”

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 `user_info` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`first_name` varchar(100) NOT NULL,
`last_name` varchar(100) NOT NULL,
`gfg_username` varchar(100) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

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

create a table ‘user_info” from the SQL panel

Insert records: We will now insert some records into our table. Here we are inserting 4 records. You can add multiple records.

records in our table

Copy and paste the following code into the SQL panel to insert records into the table.

INSERT INTO `user_info` (`first_name`, `last_name`, `gfg_username`) VALUES ('Rohit', 'Kumar', 'rohitk987'), 
('Nisha', 'Jadhav', 'nishajadhav001'), ('Aayush', 'Joshi', 'geeky1aayush'), ('Shweta', 'Pawar', 'shwetap12gfg');

inserting records

Creating folder and files:

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

folder structure

database.php: Code for connection with the database.

PHP

<?php
// this php script is for connecting with database
// data has to be fetched from local server

// 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 connections
if (!$mysqli){
    echo "Connection Unsuccessful!!!";
}

?>

index.php: Code for displaying the records.

PHP

<?php
// going to use above code
require 'database.php';

// printing column name above the data
echo 'ID'.' '.'First Name'.' '.'Last Name'.' '.'GFG Username'.'<br>';

// sql query to fetch all the data
$query = "SELECT * FROM `user_info`";
// mysql_query will execute the query to fetch data
if ($is_query_run = mysql_query($query))
{
    // echo "Query Executed";
    // loop will iterate until all data is fetched
    while ($query_executed = mysql_fetch_assoc ($is_query_run))
    {
        // these four line is for four column
        echo $query_executed['ID'].' ';
        echo $query_executed['first_ame'].' ';
        echo $query_executed['last_name'].' ';
        echo $query_executed['gfg_username'].'<br>';
    }
}
else
{
    echo "Error in execution!";
}
?>

Output:

ID First Name Last Name GFG Username
1  Rohit Kumar rohitk987
2  Nisha Jadhav nishajadhav001
3  Aayush Joshi geeky1aayush
4  Shweta Pawar shwetap12gfg
