Submitted by razormist on Friday, January 24, 2020 - 13:41.

In this tutorial we will create a Create Excel File From MySQLi Table using PHP. This code can export your MySQLi table as excel file when user click the export button. The code use header() a php built-in function that can control data sent to the browser by the Web server by customizing the output content. This a user-friendly program feel free to modify and use it to your system. We will be using PHP as a scripting language and interpreter that is used primarily on any webserver including xamp, wamp, etc. It is being use to any famous websites because of modern approach as its today.

Getting Started:

First you have to download & install XAMPP or any local server that run PHP scripts. Here's the link for XAMPP server https://www.apachefriends.org/index.html. And, this is the link for the bootstrap that i used for the layout design https://getbootstrap.com/.

Creating Database

Open your database web server then create a database name in it db_create_excel, after that click Import then locate the database file inside the folder of the application then click ok. tut1

Creating the database connection

Open your any kind of text editor(notepad++, etc..). Then just copy/paste the code below then name it conn.php.

<?php
        $conn = mysqli_connect('localhost', 'root', '', 'db_create_excel');
        
        if(!$conn){
                die("Error: Failed to connect to database!");
        }
?>

Creating The Interface

This is where we will create a simple form for our application. To create the forms simply copy and write it into your text editor, then save it as index.php.

                                </div>
                                <center><button name="save" class="btn btn-primary"><span class="glyphicon glyphicon-save"></span> Save</button></center>

                        </form>
                        <br /><br />
                        <table class="table table-bordered">
                                <thead class="alert-info">
                                        <tr>
                                                <th>Firstname</th>
                                                <th>Lastname</th>
                                                <th>Address</th>
                                        </tr>
                                </thead>
                                <tbody>
                                        <?php
                                                require 'conn.php';
                                                
                                                $query = mysqli_query($conn, "SELECT * FROM `member`");
                                                while($fetch = mysqli_fetch_array($query)){
                                        ?>
                                        <tr>
                                                <td><?php echo $fetch['firstname']?></td>
                                                <td><?php echo $fetch['lastname']?></td>
                                                <td><?php echo $fetch['address']?></td>
                                        </tr>
                                        <?php
                                                }
                                        ?>
                                </tbody>
                        </table>
                </div>
        </div>
</body>
</html>

Creating PHP Query

This code contains the php query of the application. This code will store the form inputs to the MySQLi server. To do that just copy and write this block of codes inside the text editor, then save it as save.php.

<?php
        require_once 'conn.php';
        
        if(ISSET($_POST['save'])){
                $firstname = $_POST['firstname'];
                $lastname = $_POST['lastname'];
                $address = $_POST['address'];
                
                mysqli_query($conn, "INSERT INTO `member` VALUE('', '$firstname', '$lastname', '$address')") or die(mysqli_errno());
                header('location: index.php');
                        
        }
?>

Creating the Main Function

This code contains the main function of the application. This code will export your MySQLi table as an excel when the button is clicked. To make this just copy and write these block of codes below inside the text editor, then save it as create_excel.php

<?php
        header("Content-Type: application/xls");    
        header("Content-Disposition: attachment; filename=excel.xls");  
        header("Pragma: no-cache"); 
        header("Expires: 0");
 
        require_once 'conn.php';
        
        $output = "";
        
        if(ISSET($_POST['export'])){
                $output .="
                        <table>
                                <thead>
                                        <tr>
                                                <th>ID</th>
                                                <th>Firstname</th>
                                                <th>Lastname</th>
                                                <th>Address</th>
                                        </tr>
                                <tbody>
                ";
                
                $query = mysqli_query($conn, "SELECT * FROM `member`") or die(mysqli_errno());
                while($fetch = mysqli_fetch_array($query)){
                        
                $output .= "
                                        <tr>
                                                <td>".$fetch['mem_id']."</td>
                                                <td>".$fetch['firstname']."</td>
                                                <td>".$fetch['lastname']."</td>
                                                <td>".$fetch['address']."</td>
                                        </tr>
                ";
                }
                
                $output .="
                                </tbody>
                                
                        </table>
                ";
                
                echo $output;
        }
        
?>
