PHP:使用anagram创建的结果填充MySQL表

<?php
// 连接到MySQL数据库服务器
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 创建表
$sql = "CREATE TABLE words (
    id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    word VARCHAR(30) NOT NULL,
    anagram VARCHAR(30) NOT NULL
)";

if ($conn->query($sql) === TRUE) {
    echo "表创建成功";
} else {
    echo "创建表时出错: " . $conn->error;
}

// 使用anagram函数生成并插入数据
$words = array("cat", "dog", "car", "tree");

foreach ($words as $word) {
    $anagram = str_shuffle($word); // 使用anagram函数生成新的单词
    $sql = "INSERT INTO words (word, anagram) VALUES ('$word', '$anagram')";

    if ($conn->query($sql) === TRUE) {
        echo "插入数据成功";
    } else {
        echo "插入数据时出错: " . $conn->error;
    }
}

$conn->close();
