尝试将数组插入数据库而不重复

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

// 创建数据库连接
$conn = new mysqli($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);
}

// 数组数据
$array = [1, 2, 3, 4, 5];

// 将数组转换为逗号分隔的字符串
$data = implode(',', $array);

// 检查是否已存在相同的数据
$sql = "SELECT * FROM table_name WHERE column_name = '$data'";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    echo "数据已存在，无需插入";
} else {
    // 执行插入操作
    $sql = "INSERT INTO table_name (column_name) VALUES ('$data')";
    if ($conn->query($sql) === TRUE) {
        echo "数据插入成功";
    } else {
        echo "数据插入失败: " . $conn->error;
    }
}

// 关闭数据库连接
$conn->close();
