Exporting Data to Excel using PHP & MySQL

Export Data to Excel is a common feature of web applications to allow dynamic data export to Excel file to save locally for further use. If you’re a PHP developer and thinking to implement data export to excel, then you’re here at right place. You will learn here how to implement data export to excel using PHP & MySQL.

In our previous tutorial you have learned how to export data to excel in CodeIgniter, now in this tutorial we will explain how to export data to excel with PHP and MySQL.

We will cover this tutorial step by step to create live demo to implement data export to excel with PHP and MySQL. You can also download complete source code of live.

So let’s start implementing data export to excel with PHP and MySQL. Before we begin, take a look on files structure for this example.

• index.php:
• export.php:

Step1: Create MySQL Database Table

As we will cover this tutorial with example to export data to Excel file, so first we will create MySQL database table developers to store developer records.

CREATE TABLE `developers` (
  `id` int(11) NOT NULL,
  `name` varchar(255) NOT NULL,
  `skills` varchar(255) NOT NULL,
  `address` varchar(255) NOT NULL,
  `gender` varchar(255) NOT NULL,
  `designation` varchar(255) NOT NULL,
  `age` int(11) NOT NULL,
  `image` varchar(255) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

We will also insert few records to this table.

INSERT INTO `developers` (`id`, `name`, `skills`, `address`, `gender`, `designation`, `age`, `image`) VALUES
(1, 'Smith', 'Java', 'Newyork', 'Male', 'Software Engineer', 34, 'image_1.jpg'),
(2, 'David', 'PHP', 'London', 'Male', 'Web Developer', 28, 'image_2.jpg'),
(3, 'Rhodes', 'jQuery', 'New Jersy', 'Male', 'Web Developer', 30, 'image_2.jpg'),
(4, 'Sara', 'JavaScript', 'Delhi', 'Female', 'Web Developer', 25, 'image_2.jpg'),
(5, 'Shyrlin', 'NodeJS', 'Tokiyo', 'Female', 'Programmer', 35, 'image_2.jpg'),
(6, 'Steve', 'Angular', 'London', 'Male', 'Web Developer', 28, 'image_2.jpg'),
(7, 'Cook', 'MySQL', 'Paris', 'Male', 'Web Developer', 26, 'image_2.jpg'),
(8, 'Root', 'HTML', 'Paris', 'Male', 'Web Developer', 28, 'image_2.jpg'),
(9, 'William', 'jQuery', 'Sydney', 'Male', 'Web Developer', 23, 'image_2.jpg'),
(10, 'Nathan', 'PHP', 'London', 'Male', 'Web Developer', 28, 'image_2.jpg'),
(11, 'Shri', 'PHP', 'Delhi', 'Male', 'Web Developer', 38, 'image_2.jpg'),
(12, 'Jay', 'PHP', 'Delhi, India', 'Male', 'Web Developer', 30, 'image_3.jpg');

Step2: Get Records from MySQL Database Table

In export.php file, we will get developer records from MySQL database table developers and store into an array.

include_once("db_connect.php");
$sqlQuery = "SELECT name, gender, age, skills, address, designation FROM developers LIMIT 10";
$resultSet = mysqli_query($conn, $sqlQuery) or die("database error:". mysqli_error($conn));
$developersData = array();
while( $developer = mysqli_fetch_assoc($resultSet) ) {
	$developersData[] = $developer;
}	

Step3: Display Records with Export to Excel Button

In index.php file, we will display developer records from $developersData array. We will also add data export button to export data.

<div class="container">		
	<div class="well-sm col-sm-12">
		<div class="btn-group pull-right">	
			<form action="<?php echo $_SERVER["PHP_SELF"]; ?>" method="post">					
				<button type="submit" id="dataExport" name="dataExport" value="Export to excel" class="btn btn-info">Export To Excel</button>
			</form>
		</div>
	</div>				  
	<table id="" class="table table-striped table-bordered">
		<tr>
			<th>Name</th>
			<th>Gender</th>
			<th>Age</th>
			<th>Skills</th>			
			<th>Address</th>
			<th>Designation</th>
		</tr>
		<tbody>
			<?php foreach($developersData as $developer) { ?>
			   <tr>
			   <td><?php echo $developer ['name']; ?></td>
			   <td><?php echo $developer ['gender']; ?></td>
			   <td><?php echo $developer ['age']; ?></td>  
				<td><?php echo $developer ['skills']; ?></td>			   
			   <td><?php echo $developer ['address']; ?></td>
			   <td><?php echo $developer ['designation']; ?></td>   
			   </tr>
			<?php } ?>
		</tbody>
    </table>		
</div>

Step4: Implement Data Export to Excel

Now we will implement export data to excel when export button clicked. We will use $developersData array for data exported and saved into an xlsx file.

<?php
if(isset($_POST["dataExport"])) {	
	$fileName = "webdamn_export_".date('Ymd') . ".xls";			
	header("Content-Type: application/vnd.ms-excel");
	header("Content-Disposition: attachment; filename=\"$fileName\"");	
	$showColoumn = false;
	if(!empty($developersData)) {
	  foreach($developersData as $developerInfo) {
		if(!$showColoumn) {		 
		  echo implode("\t", array_keys($developerInfo)) . "\n";
		  $showColoumn = true;
		}
		echo implode("\t", array_values($developerInfo)) . "\n";
	  }
	}
	exit;  
}
?>
