Don’t want to be eliminated? Learn these PHP development skills and earn 10K is no longer difficult

With the rapid development of the Internet, the field of web development has become a popular choice for high-paying employment. As a widely used server-side scripting language, mastering PHP development skills is crucial for those who want to stand out in the field of web development. This article will introduce some methods to improve PHP development skills, and attach code examples to help readers better understand and master these skills.

1. Familiar with the PHP framework

In PHP development, the framework is an important tool to improve development efficiency and code quality. Mastering one or more common PHP frameworks, such as Laravel, CodeIgniter, or Symfony, will enable you to develop feature-rich applications more quickly. Here is an example of creating a simple route using the Laravel framework:

Route::get('/hello', function () {
    return 'Hello, World!';
});

2. Mastering Object-Oriented Programming

Object-oriented programming (OOP) is an advanced programming technique that enables You better organize and manage your project's code. In PHP, you use classes and objects to represent real-world entities and behaviors. The following is a simple PHP class example:

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. Learn to use MySQL database

PHP and MySQL are a golden combination. Learning to use MySQL database will enable you to store and manage large amounts of data. The following is a simple example of PHP connecting to a MySQL database and inserting data:

$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_database";

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

if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

$sql = "INSERT INTO users (name, email) VALUES ('John', 'john@example.com')";

if ($conn->query($sql) === TRUE) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

$conn->close();

4. Mastering secure programming skills

Network security is an important topic, also in PHP development can not be ignored. Learn to prevent common security issues such as SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF). The following is an example of using prepared statements to prevent SQL injection:

$stmt = $conn->prepare("SELECT * FROM users WHERE username = ? AND password = ?");
$stmt->bind_param("ss", $username, $password);
$stmt->execute();
$result = $stmt->get_result();

if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        // 处理查询结果
    }
} else {
    echo "Invalid username or password";
}

$stmt->close();

5. Learn to use version control tools

Version control tools such as Git can allow you to better manage Version code and track changes. Mastering version control tools will enable you to collaborate with your team, roll back code, and resolve conflicts. The following is an example of using Git for code submission and branch switching:

// 创建新分支
$ git branch new_feature
$ git checkout new_feature

// 提交代码
$ git add .
$ git commit -m "Add new feature"

// 切换回主分支
$ git checkout master

By learning and mastering these PHP development skills, you will be able to better cope with challenges in the Internet field and stand out in the job market. Act quickly and become a high-paying PHP developer!
