How to build an efficient website using PHP native development

PHP is a very popular server-side programming language, which is widely used to develop websites and web applications. While there are many modern frameworks available for PHP, such as Laravel and Symfony, there are situations where developing natively with PHP can be more efficient and flexible. In this article, we'll cover how to build an efficient website using PHP native development and provide some code examples.

1. Configuring the environment

Before we begin, we need to make sure our environment is configured correctly. First, we need a web server such as Apache or Nginx. Secondly, we need to install PHP. You can download the latest PHP version from the official website. After installing PHP, we also need to install some commonly used extensions, such as MySQL, Redis and Memcached.

2. Use object-oriented programming style

PHP natively supports the object-oriented programming paradigm. Using object-oriented programming style can better organize the code structure and improve the readability and maintainability of the code. The following is a simple example:

class User {
    private $name;
    private $email;
    
    public function __construct($name, $email) {
        $this->name = $name;
        $this->email = $email;
    }
    
    public function getName() {
        return $this->name;
    }
    
    public function getEmail() {
        return $this->email;
    }
}

$user = new User("John Doe", "john@example.com");
echo $user->getName(); // 输出 "John Doe"
echo $user->getEmail(); // 输出 "john@example.com"

3. Using PDO for database operations

PHP natively supports PDO (PHP Data Objects), which is a light tool for accessing databases. Level of abstraction. Using PDO, we can easily connect and perform database operations. Here is an example:

$dsn = "mysql:host=localhost;dbname=mydatabase";
$username = "root";
$password = "";

try {
    $pdo = new PDO($dsn, $username, $password);
    $statement = $pdo->prepare("SELECT * FROM users WHERE id = :id");
    $statement->execute(["id" => 1]);
    $user = $statement->fetch(PDO::FETCH_ASSOC);
    echo $user["name"];
} catch (PDOException $e) {
    echo "连接数据库失败：" . $e->getMessage();
}

4. Use caching to improve performance

Caching is one of the keys to improving website performance. Using PHP natively, we can easily interact with common caching systems such as Memcached and Redis. Here is an example:

$cache = new Redis();
$cache->connect("127.0.0.1", 6379);
$key = "user_1";
$user = $cache->get($key);

if (!$user) {
    $user = getUserFromDatabase(); // 从数据库中获取用户数据
    $cache->set($key, $user, 3600); // 将用户数据缓存一小时
}

echo $user["name"];

5. Using a template engine

The template engine can help us separate logic and display, making the code easier to manage and maintain. PHP natively supports a simple template engine, such as using the include statement to include template files. Here is an example: The

$user

variable can be used in the

$user = getUserFromDatabase();

include "templates/user.php";

user.php template file to display user data.

Summary:

Using PHP native development can provide higher flexibility and customization, allowing us to better control the development process and performance of the website. In this article, we introduced how to configure the environment and use technologies such as object-oriented programming style, PDO for database operations, caching and template engines to build efficient websites. I hope these examples will be helpful to you and enable you to better use PHP to natively develop web applications.
