如何用php向数据库中插入大量数据

<?php
// 连接数据库
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_database";
$conn = new mysqli($servername, $username, $password, $dbname);

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

// 准备插入语句
$sql = "INSERT INTO your_table (column1, column2, column3) VALUES (?, ?, ?)";
$stmt = $conn->prepare($sql);

// 绑定参数
$stmt->bind_param("sss", $value1, $value2, $value3);

// 生成要插入的数据并执行插入
for ($i = 0; $i < 1000; $i++) {
    $value1 = "data" . $i;
    $value2 = "data" . ($i + 1);
    $value3 = "data" . ($i + 2);
    $stmt->execute();
}

// 关闭连接
$stmt->close();
$conn->close();
?>
