Variables & Data Types
PHP variables start with a dollar sign $. They are loosely typed — you do not declare the type. Common types: string, integer, float, boolean, array, null.
PHP
<?php
$name = "Ali"; // string
$age = 25; // integer
$price = 19.99; // float
$isActive = true; // boolean
$items = ["a", "b"]; // array
?>
