Before starting to learn PHP, you must first master the basics of front-end technologies such as HTML, CSS and JavaScript, which is very important for a full-stack developer. Said it is particularly important. Then, you need to learn PHP's syntax and features, including variables, arrays, functions, classes, namespaces, etc. Mastering the basics of PHP is the first step to building a solid technical foundation.

The following is a simple PHP code example for outputting "Hello World":

<?php
    echo "Hello World";
?>

2. Learn and apply commonly used PHP frameworks

Proficient PHP technology requires learning and proficiency in using some commonly used PHP frameworks, such as Laravel, Symfony, and CodeIgniter. These frameworks can help developers build complex web applications faster and provide functions such as database operations, routing, template engines, etc. By learning these frameworks in depth, you can better understand how PHP works and improve your development efficiency.

The following is a simple code example in the Laravel framework, used to define a route and corresponding controller method:

<?php

use IlluminateSupportFacadesRoute;

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

class HomeController {
    public function index() {

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

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

    }

    $conn->close();
?>

Reading relevant technical books, attending technical training and seminars, and joining developer communities and forums are all good ways to improve your skills. In addition, by participating in open source projects and contributing your own code, you can not only demonstrate your technical capabilities, but also gain more practical experience.

To sum up, if you want to win a high-paying position, being proficient in PHP technology is essential. By deeply studying the basic knowledge of PHP, learning and applying commonly used PHP frameworks, mastering database operation techniques, and continuing to learn and practice, you will be able to improve your technical level and achieve better career development in the Internet industry.
