How to improve your technical level by learning PHP native development

Overview:
With the rapid development of the Internet and the continuous updating of technology, as a developer, It is particularly important to continuously improve your technical level. Learning PHP native development is an effective way to further improve your technical level. This article will introduce how to improve your technical level by learning PHP native development, and attach some practical code examples.

1. Understand the advantages of PHP native development

1. Flexibility: PHP native development allows developers to fully grasp the process and logic of the code, and flexibly adjust it according to specific needs to meet project needs. High level of customization.
2. Performance optimization capability: Through PHP native development, you can deeply understand the underlying layer of PHP to achieve performance optimization. For example, optimizing database connections, queries, and caching can effectively improve the response speed of the website.
3. Rich learning resources: As a mature development language, PHP has a large number of learning resources and open source projects. By learning PHP native development, you can better understand and apply these resources.

2. Steps to learn PHP native development:

1. Understand the basic knowledge of PHP: In order to learn PHP native development, you first need to have basic knowledge of the PHP language. Includes basic knowledge of variables, data types, operators, conditionals, and loop statements.
2. Learn PHP object-oriented programming: Object-oriented programming is an important concept in PHP development, through which the maintainability and reusability of the code can be improved. Master the related concepts, features and syntax of object-oriented, such as classes, objects, inheritance, encapsulation, polymorphism, etc.

The following is a simple PHP object-oriented programming example:

class Person {
  private $name;
  private $age;

  public function __construct($name, $age) {
    $this->name = $name;
    $this->age = $age;
  }

  public function sayHello() {
    echo "Hello, I'm {$this->name}.";
  }

  public function getAge() {
    return $this->age;
  }
}

$person = new Person("John", 25);
$person->sayHello();
echo "Age: " . $person->getAge();

3. Master PHP database operations: learn how to connect to the database, perform queries, update and insert operations, etc. Master the SQL language and techniques to avoid SQL injection.

The following is a simple PHP database operation example:

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

$conn = new mysqli($servername, $username, $password, $dbname);

if ($conn->connect_error) {
  die("连接失败: " . $conn->connect_error);
}

$sql = "SELECT * FROM users";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
  while($row = $result->fetch_assoc()) {
    echo "ID: " . $row["id"] . "，用户名：" . $row["username"];
  }
} else {
  echo "0 结果";
}

$conn->close();

4. Learn commonly used PHP development frameworks: Master commonly used PHP development frameworks, such as Laravel, Symfony, etc., these The framework will provide more efficient and standardized development models and development tools to help improve development efficiency.

3. Practice and Summary
By learning PHP native development, you can better understand the underlying technology and core mechanisms of PHP, and master the flexibility and problem-solving abilities in the development process. Only through continuous practice and summary can we truly improve our technical level. During the development process, you can try to solve some problems in actual scenarios and explore new technical points. At the same time, participate in more open source projects, understand cutting-edge technology trends, and keep pace with the industry.

Conclusion
Learning PHP native development can not only improve your technical level, but also better understand the operating mechanism of other PHP development frameworks and tools, laying the foundation for further technical exploration. I hope this article will be helpful to beginners and PHP developers who want to improve their technical skills.
