csv导入mysql php实现

<?php
// 数据库连接配置
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";

// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);

// 检查连接
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 读取CSV文件
$csvFile = fopen("data.csv", "r");

if ($csvFile === false) {
    die("无法打开文件");
}

// 跳过CSV文件的标题行
fgetcsv($csvFile);

// 逐行读取CSV文件并插入数据库
while (($data = fgetcsv($csvFile)) !== false) {
    $sql = "INSERT INTO table_name (column1, column2, column3) VALUES (?, ?, ?)";
    $stmt = $conn->prepare($sql);
    $stmt->bind_param("sss", $data[0], $data[1], $data[2]);
    if ($stmt->execute()) {
        echo "记录插入成功\n";
    } else {
        echo "记录插入失败: " . $stmt->error . "\n";
    }
}

// 关闭文件和数据库连接
fclose($csvFile);
$stmt->close();
$conn->close();
