Improving your PHP development skills, getting a promotion and a salary increase of 10K is not a dream!

With the rapid development of the Internet and information technology, PHP, as a powerful server-side programming language, is loved by more and more developers. As a PHP developer, you not only need to have a solid programming foundation, but also need to continuously improve your skills to keep pace with market demand. This article will introduce some methods that can help you improve your PHP development skills, and have code examples for reference.

1. Learn and master the basic knowledge of PHP

As a programming language, PHP has its unique syntax and features. To become an excellent PHP developer, you first need to master the basic knowledge of PHP, including variables, data types, operators, flow control statements, etc. The following is a simple sample code to demonstrate the use of conditional statements:

<?php
$score = 90;

if ($score >= 60) {
    echo "及格";
} else {
    echo "不及格";
}
?>

2. Learn Object-Oriented Programming (OOP) with PHP

Object-oriented programming is modern programming One of the important features of the language and an essential part of PHP development. By learning the concepts and principles of OOP, you can better organize and manage your code, improving code reusability and maintainability. The following is a simple sample code to demonstrate the use of classes and objects:

<?php
class Person {
    private $name;

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

    public function sayHello() {
        echo "Hello, my name is " . $this->name;
    }
}

$person = new Person("Alice");
$person->sayHello();
?>

3. Mastering the PHP Framework

PHP framework can help you develop applications faster , improve development efficiency. Nowadays, there are many popular PHP frameworks to choose from, such as Laravel, Symfony, CodeIgniter, etc. Choose a framework that suits you, and learn and master it in depth. The following is a simple example code using the Laravel framework to demonstrate the use of routes and controllers:

Route Fileroutes/web.php:

Route::get('/', 'HomeController@index');

Controller Fileapp/Http/Controllers/HomeController.php：

<?php
namespace AppHttpControllers;

class HomeController extends Controller {
    public function index() {
        return view('welcome');
    }
}
?>

4. Learn database operation

The database is an important data storage and management tool. Especially important for PHP development. Learning and becoming familiar with database operations is an essential skill. You can use the native database operation functions provided by PHP (such as mysqli, PDO), or use an ORM framework (such as Eloquent) to simplify database operations. The following is a sample code for using PDO for database operations:

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

try {
    $conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    $stmt = $conn->prepare("SELECT * FROM users");
    $stmt->execute();

    $result = $stmt->fetchAll(PDO::FETCH_ASSOC);

    foreach ($result as $row) {
        echo "ID: " . $row['id'] . "，Name: " . $row['name'] . "<br />";
    }
} catch (PDOException $e) {
    echo "Error: " . $e->getMessage();
}

$conn = null;
?>

By mastering the above key points, you can improve your PHP development skills and make yourself a better PHP developer. I believe that as long as you are willing to work hard and keep learning and practicing, getting a promotion and a salary increase of 10K is not a dream!
