PHP Fundamentals

Typing: types on arguments and returns make code safer.
Array vs object: associative arrays vs class instances.
Namespaces: organize classes and prevent collisions.
Composer: the standard package manager.

Variables, functions, arrays, classes, namespaces. Modern PHP for real backends.

Minimum example (PHP 8.2)

<?php
declare(strict_types=1);

function greet(string $name): string {
    return "Hi, {$name}!";
}

echo greet("Anna");

Modern PHP is fast, typed, and pleasant. The "messy language" reputation is outdated.
