Required course for PHP development skills: build your confidence of 10K!

With the rapid development of the Internet industry, PHP, as a powerful server-side scripting language, has gradually become the first choice for developers. Having solid PHP development skills is very necessary for developers who want to gain a foothold in this industry and make breakthroughs.

In this article, I will share some required courses in PHP development skills to help you build 10K confidence and better cope with challenges in the workplace.

1. Familiar with the basic knowledge of PHP

To engage in PHP development, you must first master the basic PHP syntax and language features. For example, master the definition of variables, the use of operators, the writing of conditional statements and loop statements, etc. The following is a simple sample code that shows the basic syntax of PHP:

<?php
    $name = "John";
    $age = 25;

    echo "My name is " . $name . " and I am " . $age . " years old.";
?>

2. Master the commonly used PHP framework

The PHP framework is the mainstay of PHP development, which can greatly improve development efficiency and code quality. Currently, the more popular PHP frameworks include Laravel, Symfony, CodeIgniter, etc. The following is a sample code that uses the Laravel framework to create a simple route:

<?php
    // 导入Laravel框架
    require 'vendor/autoload.php';

    // 创建一个新的路由
    $router = new IlluminateRoutingRouter;

    // 定义一个GET请求的路由
    $router->get('/', function () {
        return 'Hello, World!';
    });

    // 执行路由
    $response = $router->dispatch(IlluminateHttpRequest::createFromGlobals());

    // 输出结果
    $response->send();
?>

3. Understand database operations

Interacting with the database is a very important part of PHP development. Therefore, it is essential to be familiar with commonly used database operation methods. MySQL is currently the most widely used relational database. The following is a sample code that uses PHP to connect to the MySQL database and execute query statements:

<?php
    // 连接MySQL数据库
    $mysqli = new mysqli("localhost", "username", "password", "database");

    // 查询语句
    $sql = "SELECT * FROM users WHERE age > 18";

    // 执行查询
    $result = $mysqli->query($sql);

    // 循环取出结果
    while ($row = $result->fetch_assoc()) {
        echo "Name: " . $row["name"] . ", Email: " . $row["email"];
    }

    // 关闭数据库连接
    $mysqli->close();
?>

4. Master object-oriented programming

Object-oriented programming is An important idea and method in modern software development. In PHP development, mastering object-oriented programming can help you better organize and manage code, and improve the maintainability and scalability of code. The following is a sample code of a PHP class using object-oriented programming:

<?php
    // 定义一个Person类
    class Person {
        private $name;
        private $age;

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

        // 获取名称方法
        public function getName() {
            return $this->name;
        }

        // 获取年龄方法
        public function getAge() {
            return $this->age;
        }
    }

    // 创建一个Person对象
    $person = new Person("John", 25);

    // 输出结果
    echo "My name is " . $person->getName() . " and I am " . $person->getAge() . " years old.";
?>

Above, I introduced some required courses in PHP development skills to help you build 10K confidence. Of course, in addition to these basic knowledge, continuous learning and practice are also very important. I believe that through continuous efforts, you will be able to achieve greater success in the field of PHP development!
