PHP 7 SimpleXLSXGen Script to Export HTML Table Data to Excel File and Download it in Browser

Welcome folks today in this blog post we will be using the SimpleXLSXGen library in php to export to the html5 table to excel file and download it inside browser. All the full source code of the application is shown below.

Get Started

In order to get started you need to start the xammp control panel and then start the apache server and mysql database as shown below

And now we will be creating the database and the table users as shown below

As you can see we have four columns inside the users table which include the id which is the primary key and it contains the Name , Age and Country of the user. Now we can insert some sample data as shown below

Directory Structure of App

And now we need to create the dbConfig.php file and copy paste the following code

dbConfig.php

<?php

$hostname = "localhost";
$username = "root";
$password = "";
$database = "usersdb";

$conn = new mysqli($hostname, $username, $password, $database);

<?php

$hostname = "localhost";

$username = "root";

$password = "";

$database = "usersdb";

$conn = new mysqli($hostname, $username, $password, $database);

As you can see we are first of all connecting to the mysql database and here we are providing the hostname and then we are providing the username, password and database.

Adding the SimpleXLSXGen Library

Now we need to create the SimpleXLSXGen.php file and copy paste the library code of php as shown below

SimpleXLSXGen.php

Displaying Data in Table

Now guys we will be creating the index.php file where we will be reading the data from the mysql table and displaying it inside the bootstrap table as shown below

index.php

As you can see we are using the select statement to fetch all the data from the mysql table and displaying it inside the bootstrap table and also we have the export button to download the excel file

Exporting HTML5 Table to Excel

Now we will making the export.php file which will actually export the data present inside the table to excel file and download it as an attachment in browser.

export.php

<?php

// Include Database connection
include("dbConfig.php");
// Include SimpleXLSXGen library
include("SimpleXLSXGen.php");

$users = [
  ['ID','Name','Age','Country']
];

$id = 0;
$sql = "SELECT * FROM users";
$res = mysqli_query($conn, $sql);
if (mysqli_num_rows($res) > 0) {
  foreach ($res as $row) {
    $id++;
    $users = array_merge($users, array(array($id, $row['Name'], $row['Age'], $row['Country'])));
  }
}

$xlsx = SimpleXLSXGen::fromArray($users);
$xlsx->downloadAs('employees.xlsx'); // This will download the file to your local system

<?php

// Include Database connection

include("dbConfig.php");

// Include SimpleXLSXGen library

include("SimpleXLSXGen.php");

$users = [

['ID','Name','Age','Country']

];

$id = 0;

$sql = "SELECT * FROM users";

$res = mysqli_query($conn, $sql);

if (mysqli_num_rows($res) > 0) {

foreach ($res as $row) {

$id++;

$users = array_merge($users, array(array($id, $row['Name'], $row['Age'], $row['Country'])));

}

$xlsx = SimpleXLSXGen::fromArray($users);

$xlsx->downloadAs('employees.xlsx'); // This will download the file to your local system

As you can see we are importing the dbConfig.php file for database connection and also we are importing the SimpleXLSXGen.php file and then we are selecting the data using the select statement and then converting the data to an array using the array_merge() method and then downloading the file as an excel file using the downloadAs() method of the library.
