Export data feature is very useful where the data is saved on the local drive for offline uses. Export data to file functionality provides a user-friendly way to maintain a large number of data in the web application. There are various file formats are available to export data and download it as a file. Microsoft Excel is a widely used spreadsheet format that organizes and maintains data.
Generally, export data functionality is used in the data management section of the web application. Excel is the best format to export data in a file and you can easily export data to excel using PHP. In this tutorial, we will show you how to export data to Excel in PHP.
The example PHP script lets you integrate export data to excel functionality. With one click, the user can export data from the MySQL database to Excel and download it in MS Excel file format (.xls/.xlsx).
Export Data to Excel with PHP
In this example script, we will export data from the array (defined in the script) to an excel file.
The $data variable holds the data in array format which will be exported to Excel using PHP.
$data = array(
array("NAME" => "John Doe", "EMAIL" => "john.doe@gmail.com", "GENDER" => "Male", "COUNTRY" => "United States"),
array("NAME" => "Gary Riley", "EMAIL" => "gary@hotmail.com", "GENDER" => "Male", "COUNTRY" => "United Kingdom"),
array("NAME" => "Edward Siu", "EMAIL" => "siu.edward@gmail.com", "GENDER" => "Male", "COUNTRY" => "Switzerland"),
array("NAME" => "Betty Simons", "EMAIL" => "simons@example.com", "GENDER" => "Female", "COUNTRY" => "Australia"),
array("NAME" => "Frances Lieberman", "EMAIL" => "lieberman@gmail.com", "GENDER" => "Female", "COUNTRY" => "United Kingdom")
);
The filterData() function is used to filter string before added to the excel sheet row.
function filterData(&$str){
$str = preg_replace("/\t/", "\\t", $str);
$str = preg_replace("/\r?\n/", "\\n", $str);
if(strstr($str, '"')) $str = '"' . str_replace('"', '""', $str) . '"';
}
The following code helps to export data in excel and download it as a file.
- The
$fileNamevariable defines the name of the excel file. - The Content-Disposition and Content-Type headers force the excel file to download.
- Run the loop through each key/value pair in the
$dataarray. - Display column names as the first row using the
$flagvariable. - The PHP array_walk() function is used to filter the data together with
filterData()function.
// Excel file name for download
$fileName = "codexworld_export_data-" . date('Ymd') . ".xlsx";
// Headers for download
header("Content-Disposition: attachment; filename=\"$fileName\"");
header("Content-Type: application/vnd.ms-excel");
$flag = false;
foreach($data as $row) {
if(!$flag) {
// display column names as first row
echo implode("\t", array_keys($row)) . "\n";
$flag = true;
}
// filter data
array_walk($row, 'filterData');
echo implode("\t", array_values($row)) . "\n";
}
exit;
Export Data from Database to Excel with PHP and MySQL
In this example script, we will export data from the MySQL database in an excel file using PHP.
Create Database Table:
For this example, we will create a members table with some basic fields in the MySQL database. The members table holds the records which will be exported to excel.
CREATE TABLE `members` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`first_name` varchar(25) COLLATE utf8_unicode_ci NOT NULL,
`last_name` varchar(25) COLLATE utf8_unicode_ci NOT NULL,
`email` varchar(50) COLLATE utf8_unicode_ci NOT NULL,
`gender` enum('Male','Female') COLLATE utf8_unicode_ci NOT NULL,
`country` varchar(20) COLLATE utf8_unicode_ci NOT NULL,
`created` datetime NOT NULL,
`status` tinyint(1) NOT NULL DEFAULT 1 COMMENT '1=Active | 0=Inactive',
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
Database Configuration (dbConfig.php):
The following code is used to connect the database using PHP and MySQL. Specify the database host ($dbHost), username ($dbUsername), password ($dbPassword), and name ($dbName) as per your database credentials.
<?php
// Database configuration
$dbHost = "localhost";
$dbUsername = "root";
$dbPassword = "root";
$dbName = "codexworld";
// Create database connection
$db = new mysqli($dbHost, $dbUsername, $dbPassword, $dbName);
// Check connection
if ($db->connect_error) {
die("Connection failed: " . $db->connect_error);
}
Export Data from Database:
The following code helps to export data from the MySQL database and download it as an excel file.
- The
filterData()function is used to filter string before added to the excel data row. $fileName– Define the name of the excel file to be downloaded.$fields– Define the column named of the excel sheet.$excelData– Add the first row to the excel sheet as a column name.- Fetch member’s data from the database and add to the row of the excel sheet.
- Define headers to force the file to download.
- Render data of excel sheet.
<?php
// Load the database configuration file
include_once 'dbConfig.php';
// Filter the excel data
function filterData(&$str){
$str = preg_replace("/\t/", "\\t", $str);
$str = preg_replace("/\r?\n/", "\\n", $str);
if(strstr($str, '"')) $str = '"' . str_replace('"', '""', $str) . '"';
}
// Excel file name for download
$fileName = "members-data_" . date('Y-m-d') . ".xls";
// Column names
$fields = array('ID', 'FIRST NAME', 'LAST NAME', 'EMAIL', 'GENDER', 'COUNTRY', 'CREATED', 'STATUS');
// Display column names as first row
$excelData = implode("\t", array_values($fields)) . "\n";
// Fetch records from database
$query = $db->query("SELECT * FROM members ORDER BY id ASC");
if($query->num_rows > 0){
// Output each row of the data
while($row = $query->fetch_assoc()){
$status = ($row['status'] == 1)?'Active':'Inactive';
$lineData = array($row['id'], $row['first_name'], $row['last_name'], $row['email'], $row['gender'], $row['country'], $row['created'], $status);
array_walk($lineData, 'filterData');
$excelData .= implode("\t", array_values($lineData)) . "\n";
}
}else{
$excelData .= 'No records found...'. "\n";
}
// Headers for download
header("Content-Type: application/vnd.ms-excel");
header("Content-Disposition: attachment; filename=\"$fileName\"");
// Render excel data
echo $excelData;
exit;
