Import Excel Data into MySQL Using PHP: A Comprehensive Guide

Excel files often serve as a primary source for data management and analysis. However, integrating the data from these files into a MySQL database requires a solid understanding of the PHP programming language and appropriate libraries. This article will guide you through the process of importing Excel data into MySQL using the PhpSpreadsheet library. We will provide a step-by-step guide with a sample code snippet to help you get started.

Step 1: Install PhpSpreadsheet

To begin, you need to install the PhpSpreadsheet library via Composer. If you do not have Composer installed, you can download it from here. After installing Composer, run the following command in your project directory:

$ composer require phpoffice/phpspreadsheet

Step 2: Create a PHP Script

Here is a sample PHP script that demonstrates how to import data from an Excel file into a MySQL database:

require __DIR__ . '';
use PhpOfficePhpSpreadsheetIOFactory;
// Database connection parameters
$host  'localhost';
$dbname  'your_database';
$username  'your_username';
$password  'your_password';
try {
    // Create a new PDO instance
    $pdo  new PDO("mysql:host$host;dbname$dbname", $username, $password);
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    // Load the Excel file
    $spreadsheet  IOFactory::load('path/to/your/file.xlsx');
    $sheetData  $spreadsheet->getActiveSheet()->toArray(null, true, true, true);
    // Prepare the SQL statement
    $stmt  $pdo->prepare("INSERT INTO your_table (column1, column2, column3) VALUES (:column1, :column2, :column3)");
    // Loop through each row of the spreadsheet
    foreach ($sheetData as $row) {
        // Skip the header row if your Excel file has one
        if ($row["A"]  "Header1") {
            continue;
        }
        // Bind the parameters and execute
        $stmt->bindParam(":column1", $row["A"]);
        $stmt->bindParam(":column2", $row["B"]);
        $stmt->bindParam(":column3", $row["C"]);
        $stmt->execute();
    }
    echo 'Data imported successfully.';
} catch (PDOException $e) {
    echo 'Error: ' . $e->getMessage();
} catch (Exception $e) {
    echo 'General Error: ' . $e->getMessage();
}

Explanation of the Code

Database Connection: Modify the database connection parameters host, dbname, username, password to match your MySQL database settings. Load Excel File: The IOFactory::load method reads the Excel file. Replace 'path/to/your/file.xlsx' with the actual path to your Excel file. Prepare SQL Statement: The SQL statement is prepared with placeholders for the values you want to insert. Loop Through Rows: The code loops through each row of the spreadsheet. If your Excel file has a header row, you can skip it by checking the first column value. Bind and Execute: The values from the Excel rows are bound to the SQL statement and executed.

Additional Notes

Ensure your MySQL table your_table and columns column1, column2, column3 match the data you are importing. Handle data types appropriately if your Excel data contains different types, such as dates or numbers. You may want to add error handling or logging for production use.

This should give you a good starting point for importing Excel data into MySQL using PHP. By following the steps and understanding the code, you can streamline your data management processes and enhance your data analysis capabilities.
