For those who work with databases and need to constantly import and export data, knowing how to import Excel data into MySQL databases is a crucial skill. This task can be easily accomplished using PHP, a popular web programming language.
Why is importing Excel data to MySQL important?
First of all, it saves time and minimizes the risk of errors that may come with manual data entry. Secondly, it allows users to quickly migrate data from an Excel file to a MySQL database, making the information accessible and easy to work with.
How to Import Excel Data into MySQL using PHP?
The first step is to create a PHP script that will access the Excel file and convert its contents into a format that can be inserted into a MySQL database. This can be achieved using the PHPExcel library, a collection of PHP classes that allows developers to read and write Excel files.
Assuming that the Excel file already exists and contains the data that needs to be imported, the following steps outline how to create a PHP script that will import the data:
Step 1: Include the PHPExcel library
Begin by including the PHPExcel library at the top of the PHP script:
<?php
require_once 'path/to/PHPExcel/Classes/PHPExcel.php';
?>
Step 2: Load the Excel file
The next step is to load the Excel file into a PHPExcel object:
<?php
// Create a new PHPExcel object
$objPHPExcel = new PHPExcel();
// Load the Excel file
$objPHPExcel = PHPExcel_IOFactory::load('path/to/excel/file.xls');
?>
Step 3: Prepare the database connection
Before inserting the data into the database, establish a connection to the MySQL database:
<?php
// Establish a connection to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error)
die("Connection failed: " . $conn->connect_error);
?>
Step 4: Prepare the MySQL query
Before inserting the data, prepare the MySQL query that will insert the data into the table:
<?php
// Prepare the MySQL query
$query = "INSERT INTO table_name (column_1, column_2, column_3) VALUES (?, ?, ?)";
// Prepare the MySQL statement
$stmt = $conn->prepare($query);
?>
Step 5: Iterate through the Excel data and insert it into the database
The final step is to iterate through the rows in the Excel file and insert the data into the MySQL database:
<?php
// Iterate through the rows of the Excel file
foreach ($objPHPExcel->getWorksheetIterator() as $worksheet)
$worksheetTitle = $worksheet->getTitle();
$highestRow = $worksheet->getHighestRow();
$highestColumn = $worksheet->getHighestColumn();
$highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);
// Iterate through each row of the Excel file
for ($row = 2; $row <= $highestRow; ++$row)
// Get the values from the Excel file
$colA = $worksheet->getCellByColumnAndRow(0, $row)->getValue();
$colB = $worksheet->getCellByColumnAndRow(1, $row)->getValue();
$colC = $worksheet->getCellByColumnAndRow(2, $row)->getValue();
// Bind the values to the MySQL statement
$stmt->bind_param("sss", $colA, $colB, $colC);
// Execute the MySQL statement
$stmt->execute();
?>
FAQ
1. Can I import Excel data into a specific MySQL table?
Yes, you can specify the table into which the data should be imported by modifying the MySQL query in Step 4 of the PHP script. Replace “table_name” with the name of the table you want to import the data into.
2. What if my Excel file contains multiple worksheets?
If your Excel file contains multiple worksheets, you can iterate through each worksheet and import the data into the database as shown in Step 5 of the PHP script. To iterate through each worksheet, use the getWorksheetIterator() method.
