Want to get 10K? Learn these PHP development skills to help you successfully break through

As a popular back-end programming language, PHP plays an important role in web development. Mastering some core PHP development skills can not only improve our technical level as developers, but also help us obtain higher salaries. If you want to succeed in the PHP development field and get a salary of more than 10K, then the following skills are what you need to learn.

1. Familiar with PHP syntax and basic knowledge
   As a qualified PHP developer, it is essential to be familiar with the basic knowledge and syntax of PHP. Understanding the basic knowledge of PHP data types, operators, control structures, etc., and being able to correctly use language features such as variables, arrays, and strings are the basis for building efficient and reliable PHP applications.

<?php
  // PHP语法示例
  $name = 'John';
  $age = 25;
  
  if ($age >= 18) {
    echo "Hello, $name! You are an adult.";
  } else {
    echo "Hello, $name! You are a minor.";
  }
?>

2. Mastering Object-Oriented Programming (OOP)
   Object-oriented programming is an integral part of modern PHP development. By using classes, objects, properties, and methods, we can better organize and manage our code. Mastering OOP concepts and principles, such as encapsulation, inheritance, and polymorphism, is critical to building scalable and maintainable applications.

<?php
  // 使用类和对象
  class Person {
    private $name;
    
    public function __construct($name) {
      $this->name = $name;
    }
    
    public function sayHello() {
      echo "Hello, my name is {$this->name}.";
    }
  }
  
  $person = new Person('John');
  $person->sayHello();
?>

3. Familiar with MySQL database operations
   The combination of PHP and MySQL is often used to build dynamic websites and applications. It is essential to understand basic operations such as SQL query language, table and field operations, and data addition, deletion, modification, and query. At the same time, learning techniques to prevent SQL injection attacks and optimize database queries is also the key to improving PHP development efficiency.

<?php
  // 使用PHP操作MySQL数据库
  $conn = mysqli_connect("localhost", "username", "password", "database");
  
  $sql = "SELECT * FROM users WHERE username = 'admin' AND password = '123456'";
  $result = mysqli_query($conn, $sql);
  
  if (mysqli_num_rows($result) > 0) {
    echo "Login successful.";
  } else {
    echo "Invalid username or password.";
  }
?>

4. In-depth understanding of PHP framework
   Learning and mastering popular PHP frameworks, such as Laravel, Symfony, CodeIgniter, etc., can help us develop and organize PHP applications more efficiently. The framework provides many useful features and functions, such as routing, Model-View-Controller (MVC) pattern, database abstraction layer, etc., allowing us to build complex applications faster.

<?php
  // Laravel框架中的路由示例
  Route::get('/hello', function () {
    return 'Hello, world!';
  });
  
  // Laravel框架中的控制器示例
  class UserController extends Controller {
    public function index() {
      $users = User::all();
      return view('users', ['users' => $users]);
    }
  }
?>

5. Learn front-end technology
   In addition to back-end development technology, it is also very helpful to master some front-end development skills. Proficient use of front-end technologies such as HTML, CSS and JavaScript can build better user interfaces and user experiences, improving our competitiveness as full-stack developers.

To sum up, if we want to successfully break through in the field of PHP development and get a salary of more than 10K, we need to master PHP syntax and basic knowledge, object-oriented programming, MySQL database operations, popular PHP frameworks and Some front-end technology. Through continuous learning and practice, and improving our technical level, we can stand out in this highly competitive industry and obtain better career development and salary returns.
