How to Export data to CSV file from Database using XAMPP ?

Last Updated : 09 May, 2022

In this article, we are going to load the data present in the database (MySQL) into CSV file. Display the data in the database and also export that data into CSV file. We are using XAMPP tool to store locally in a database.

XAMPP stands for cross-platform, Apache, MySQL, PHP, and Perl. It is among the simple light-weight local servers for website development.

Steps:

Create database and create table in your XAMPP server(MySQL ) database.
Write PHP Script to access that data
Verify results

Scenario with CSV: Create two PHP scripts named index.php and export.php Place these files in xampp/htdocs/folder/

index.php: Display the columns along with data using mysqli_fetch_array. The fetch_array() / mysqli_fetch_array() function fetches a result row as an associative array, a numeric array, or both.

Execution Steps:

1. Open XAMPP Server and start Apache and MySQL server

2. Create database with name "article_geeksdata"

3. Create table inside this database named "geeksdata" and insert data

Open Notepad and type the following code. Save this file as index.php

PHP

<?php  

// Connect syntax
 $connect = mysqli_connect("localhost", 
    "root", "", "article_geeksdata");  

// Display data from geeksdata table
 $query ="SELECT * FROM geeksdata";  

// Storing it in result variable
 $result = mysqli_query($connect, $query);  
 ?>

// HTML code to display our data
// present in table

Now open another page in notepad and type the following code. Save this file as export.php

PHP

<?php  

// Checking data by post method
if(isset($_POST["export"])) {  

    // Connect to our data base
    $connect = mysqli_connect("localhost", 
        "root", "", "article_geeksdata");  

    // Accept csv or text files
    header('Content-Type: text/csv; charset=utf-8');  

    // Download csv file as geeksdata.csv
    header('Content-Disposition: attachment; 
        filename=geeksdata.csv');  

    // Storing data 
    $output = fopen("php://output", "w");  

    // Placing data using fputcsv
    fputcsv($output, array('User_ID','Name', 
    'Article_Name', 'Article_Type', 'Data_published'));  

    // SQL query to fetch data from our table
    $query = "SELECT * from geeksdata";  

    // Result
    $result = mysqli_query($connect, $query);  

    while($row = mysqli_fetch_assoc($result)) {  

        // Fetching all rows of data one by one
        fputcsv($output, $row);

    // Closing tag
    fclose($output);
