PHPExcel如何从单元格获取数据并添加到数据库

<?php
// 导入PHPExcel库
require_once 'PHPExcel/PHPExcel.php';

// 打开Excel文件
$excelFile = 'path/to/excel/file.xlsx';
$excel = PHPExcel_IOFactory::load($excelFile);

// 选择工作表
$sheet = $excel->getActiveSheet();

// 获取单元格数据
$data = $sheet->getCell('A1')->getValue();

// 连接数据库
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// 检查连接是否成功
if ($conn->connect_error) {
    die("数据库连接失败: " . $conn->connect_error);
}

// 添加数据到数据库
$sql = "INSERT INTO table_name (column_name) VALUES ('$data')";

if ($conn->query($sql) === TRUE) {
    echo "数据添加成功";
} else {
    echo "数据添加失败: " . $conn->error;
}

// 关闭Excel文件和数据库连接
$excel->disconnectWorksheets();
unset($excel);
$conn->close();
?>
