So guys, to export data to excel sheet using php, we need to create a html form and submit the form request with post method which will be downloading the file Xlsx, Xls, Csv using code. Let's get started:

We will be using Bootstrap 5 to design the FORM or user interface.

Step 1: Download/Install the Package (phpSpreadSheet):

HP@HP-PC MINGW64 /c/xampp/htdocs/php-excel
$ composer require phpoffice/phpspreadsheet

Step 2: Create a index.php file and paste the below form:

<?php session_start(); ?>
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>How to Export Data from database in excel sheet using PHP</title>
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.1.3/dist/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
   
    <div class="container">
        <div class="row">
            <div class="col-md-12 mt-4">

                <?php
                if(isset($_SESSION['message']))
                {
                    echo "<h4>".$_SESSION['message']."</h4>";
                    unset($_SESSION['message']);
                }
                ?>

                <div class="card mt-5">
                    <div class="card-header">
                        <h4>How to Export Data from database in excel sheet using PHP</h4>
                    </div>
                    <div class="card-body">

                        <form action="code.php" method="POST">

                            <select name="export_file_type" class="form-control">
                                <option value="xlsx">XLSX</option>
                                <option value="xls">XLS</option>
                                <option value="csv">CSV</option>
                            </select>

                            <button type="submit" name="export_excel_btn" class="btn btn-primary mt-3">Export</button>

                        </form>

                    </div>
                </div>

            </div>
        </div>
    </div>

    <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.1.3/dist/js/bootstrap.bundle.min.js"></script>
</body>
</html>


Step 3: Create a table named students in your database as follows:

CREATE TABLE students (
    id INT(11) AUTO_INCREMENT PRIMARY KEY,
    fullname VARCHAR(191) NOT NULL,
    email VARCHAR(191) NOT NULL,
    phone VARCHAR(191) NOT NULL,
    course VARCHAR(191) NOT NULL
)


Step 4: Create a code.php file and paste the below code:

<?php
session_start();
$con = mysqli_connect('localhost','root','','adminpanel');

require 'vendor/autoload.php';

use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
use PhpOffice\PhpSpreadsheet\Writer\Xls;
use PhpOffice\PhpSpreadsheet\Writer\Csv;

if(isset($_POST['export_excel_btn']))
{
    $file_ext_name = $_POST['export_file_type'];
    $fileName = "student-sheet";

    $student = "SELECT * FROM students";
    $query_run = mysqli_query($con, $student);

    if(mysqli_num_rows($query_run) > 0)
    {
        $spreadsheet = new Spreadsheet();
        $sheet = $spreadsheet->getActiveSheet();

        $sheet->setCellValue('A1', 'ID');
        $sheet->setCellValue('B1', 'Full Name');
        $sheet->setCellValue('C1', 'Email');
        $sheet->setCellValue('D1', 'Phone');
        $sheet->setCellValue('E1', 'Course');

        $rowCount = 2;
        foreach($query_run as $data)
        {
            $sheet->setCellValue('A'.$rowCount, $data['id']);
            $sheet->setCellValue('B'.$rowCount, $data['fullname']);
            $sheet->setCellValue('C'.$rowCount, $data['email']);
            $sheet->setCellValue('D'.$rowCount, $data['phone']);
            $sheet->setCellValue('E'.$rowCount, $data['course']);
            $rowCount++;
        }

        if($file_ext_name == 'xlsx')
        {
            $writer = new Xlsx($spreadsheet);
            $final_filename = $fileName.'.xlsx';
        }
        elseif($file_ext_name == 'xls')
        {
            $writer = new Xls($spreadsheet);
            $final_filename = $fileName.'.xls';
        }
        elseif($file_ext_name == 'csv')
        {
            $writer = new Csv($spreadsheet);
            $final_filename = $fileName.'.csv';
        }

        // $writer->save($final_filename);
        header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
        header('Content-Disposition: attactment; filename="'.urlencode($final_filename).'"');
        $writer->save('php://output');

    }
    else
    {
        $_SESSION['message'] = "No Record Found";
        header('Location: index.php');
        exit(0);
    }
}

?>
