使用PHP将值插入MySQL表

$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "mydatabase";

// 使用mysqli扩展连接到MySQL数据库
$conn = new mysqli($servername, $username, $password, $dbname);

// 使用PDO扩展连接到MySQL数据库
$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);

$tableName = "mytable";
$column1 = "column1";
$column2 = "column2";
$value1 = "value1";
$value2 = "value2";

$sql = "INSERT INTO $tableName ($column1, $column2) VALUES ('$value1', '$value2')";

// 使用mysqli扩展执行SQL语句
if ($conn->query($sql) === TRUE) {
    echo "数据插入成功";
} else {
    echo "数据插入失败: " . $conn->error;
}

// 使用PDO扩展执行SQL语句
if ($conn->exec($sql)) {
    echo "数据插入成功";
} else {
    echo "数据插入失败";
}

// 使用mysqli扩展关闭数据库连接
$conn->close();

// 使用PDO扩展关闭数据库连接
$conn = null;
