Introduction:
In the current rapidly changing Internet era, the demand for PHP developers continues to increase. However, getting a well-paying job is not easy. This article will introduce you to a method to achieve a 10K salary breakthrough by gradually improving your PHP development skills. At the same time, we will provide some practical code examples to help you better understand and apply these skills.

To become an excellent PHP developer, you must first master the basic knowledge of PHP. You can start to learn PHP's syntax, data types, functions, flow control statements, etc. The following is a simple PHP code example for outputting a "Hello, World!" message:

<?php
  echo "Hello, World!";
?>

Step 2: In-depth understanding of object-oriented programming (OOP)
Object-oriented programming is PHP development a very important part of. Mastering OOP can make your code easier to maintain and extend. You can learn PHP concepts such as classes, objects, inheritance, and polymorphism, and at the same time, you can use some common design patterns to improve the quality of your code. The following is a simple PHP OOP code example for creating a student class and calling methods in it:

<?php
  class Student {
    public $name;
    public $age;

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

    public function printInfo() {
      echo "My name is " . $this->name . ", and I am " . $this->age . " years old.";
    }
  }

  $student = new Student("Tom", 20);
  $student->printInfo();
?>

Step 3: Learn to use commonly used PHP frameworks
Learning and using PHP frameworks is the best way to improve development Key to efficiency and code quality. Currently, popular PHP frameworks include Laravel, CodeIgniter, Symfony, etc. You can choose one of the frameworks to learn and use the features and tools it provides to develop projects. The following is a simple code example based on the Laravel framework to create a simple web page routing:

<?php
  Route::get('/', function () {
    return view('welcome');
  });
?>

Step 4: Learn to use the database

<?php
  $servername = "localhost";
  $username = "root";
  $password = "";
  $dbname = "test";

  // 创建连接
  $conn = new mysqli($servername, $username, $password, $dbname);

  // 检测连接
  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 "姓名: " . $row["name"]. " - 年龄: " . $row["age"]. "<br>";
    }
  } else {
    echo "0 结果";
  }
  
  $conn->close();
?>

End:
By learning the above 4 steps, you can gradually improve your PHP development skills and find a job Show your strength. Of course, in addition to technological advancement, continuous learning, practice and accumulation of project experience are also required. I believe you will eventually be able to achieve greater breakthroughs in the field of PHP development and reach the goal of 10K salary!

The above are just some simple sample codes, and the situation in actual projects may be more complex. I hope these examples can help you understand the corresponding skill points and apply them in actual projects. I wish you go further and further on the road of PHP development and gain more success and achievements!
