1. In-depth understanding of the basic knowledge of PHP

As an excellent PHP programmer, it is very important to have an in-depth understanding of the basic knowledge of PHP. Master PHP's syntax and function library, and be able to flexibly use PHP's data types, conditional statements and loop structures to write efficient and easy-to-maintain code.

The following is a simple PHP code example that demonstrates how to use conditional statements and loop structures:

<?php
// 条件语句示例
$score = 80;
if($score >= 60) {
    echo '及格';
} else {
    echo '不及格';
}

// 循环结构示例
for($i = 1; $i <= 5; $i++) {
    echo $i . ' ';
}
?>

2. Familiar with PHP frameworks

PHP has many popular frameworks, such as Laravel, CodeIgniter and Yii, etc. Familiarity with these frameworks can help you develop projects more quickly and efficiently. These frameworks provide many ready-made functional modules and code libraries, reducing development workload and improving production efficiency.

The following is an example using the Laravel framework to show how to create a simple web application:

// 首先在终端运行以下命令安装Laravel框架
composer global require laravel/installer

// 创建新项目
laravel new myapp

// 进入项目目录
cd myapp

// 启动开发服务器
php artisan serve

3. Database operation skills

Interaction with the database in web development is very common, so it is important to master PHP database operation skills. Using PHP's database extensions, such as MySQLi and PDO, you can easily connect to the database, perform query and update operations.

The following is an example using MySQLi extension to show how to connect to the database and perform query operations:

// 连接数据库
$conn = new mysqli('localhost', 'username', 'password', 'database');

// 检查连接
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 执行查询
$sql = "SELECT * FROM users";
$result = $conn->query($sql);

// 输出查询结果
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        echo $row["name"] . " " . $row["email"];
    }
} else {
    echo "0 结果";
}

// 关闭连接
$conn->close();

4. Combination of front-end and back-end technologies

With the development of front-end and back-end separation architecture With the rise of technology, mastering some front-end technologies is also the key to improving competitiveness. PHP can be combined with front-end technologies such as HTML, CSS and JavaScript to achieve richer and more dynamic web applications.

Here is an example using a combination of PHP and JavaScript to show how to implement asynchronous data requests through AJAX:

// PHP处理AJAX请求
if(isset($_GET['username'])) {
    $username = $_GET['username'];
    echo 'Hello, ' . $username;
}

// JavaScript发起AJAX请求
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
    if (xhr.readyState === 4 && xhr.status === 200) {
        console.log(xhr.responseText);
    }
};
xhr.open('GET', 'ajax.php?username=John', true);
xhr.send();

By learning and mastering these PHP skills, you will be better able to cope with your job challenges, enhance one's professional competitiveness, and be able to escape from the predicament of low salary. Take action now and become an excellent PHP programmer!
