The internet industry is rapidly growing, and PHP, as a widely used server-side programming language, has become a fundamental technology for many enterprises. With rising market demand, PHP developers’ salaries have also increased. To earn 10K, you must have solid technical skills and rich development experience.
PHP syntax is similar to C language, simple and easy to learn. However, a solid foundation is required for deeper mastery.
// Output Hello World!
echo "Hello World!";
The echo statement outputs a string and is commonly used for debugging, essential for beginners.
PHP supports multiple data types including integers, floats, strings, arrays, objects, and null. Understanding storage, operations, and type conversion methods is fundamental.
// Declare and access array
$fruits = array("Apple", "Banana", "Orange");
echo $fruits[0];
array defines an array, and elements are accessed via indices.
PHP supports object-oriented programming with functions and classes. Beginners can start with built-in string, date/time, and file handling functions, then progress to custom functions and classes.
// Custom function
function add($a, $b) {
return $a + $b;
}
echo add(5, 3);
This code defines an add function that sums two parameters and outputs the result.
HTML and CSS are the foundations of web front-end development. Mastering HTML tag structures and CSS styling helps create visually appealing and user-friendly webpages.
<!-- HTML example -->
<h1>This is a heading</h1>
<p>This is a paragraph.</p>
/* CSS styles */
h1 {
color: red;
font-size: 36px;
}
The example shows h1 and p tags defining a heading and paragraph, with CSS controlling color and font size.
JavaScript powers dynamic web interactions. Learning basic syntax and event handling enhances page interactivity and user experience.
// JavaScript example
var name = "John";
alert("Hello " + name);
This example demonstrates variable declaration and a pop-up alert with string concatenation.
MySQL is a widely used relational database system essential for backend web development. Understanding its syntax and design principles helps build efficient data storage.
// Create table
CREATE TABLE Persons (
PersonID int,
LastName varchar(255),
FirstName varchar(255),
Address varchar(255),
City varchar(255)
);
The SQL statement creates a table named Persons with various fields and types.
Laravel is a modern PHP web framework using the MVC architecture, offering rich features and plugins. Mastering routing, controllers, models, and views can greatly improve development efficiency.
// Laravel routing example
Route::get('/user/{id}', function ($id) {
return 'User ' . $id;
});
This code defines a dynamic route where {id} is a parameter for different user access.
ThinkPHP is a popular open-source Chinese PHP framework with strong community support and documentation. Mastering routing, controllers, and models helps speed up enterprise-level web app development.
// ThinkPHP routing example
Route::rule('/user/:id', 'index/user', 'GET');
This defines a route path and corresponding controller method, passing parameters in requests.
To earn 10K as a PHP developer, you need solid PHP fundamentals, proficiency in web development technologies, and mastery of mainstream PHP frameworks. Continuously improving these skills will help you stand out in a competitive job market and achieve both career and salary growth.
