一个php页面中的MYSQL多选查询

<?php
// 连接数据库
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_database";

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

// 获取多选条件值
$conditions = $_POST['conditions']; // 假设条件值通过POST方式提交

// 构建查询语句
$sql = "SELECT * FROM your_table WHERE your_column IN ('" . implode("','", $conditions) . "')";

// 执行查询
$result = $conn->query($sql);

// 显示结果
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        echo "字段1: " . $row["column1"] . ", 字段2: " . $row["column2"] . "<br>";
    }
} else {
    echo "没有符合条件的结果";
}

// 关闭数据库连接
$conn->close();
?>
