What are some methods to document PHP code, including variables?

One method to document PHP code, including variables, is to use inline comments to provide explanations for each variable and its purpose. Another method is to use PHPDoc comments above functions and classes to provide detailed documentation for variables, parameters, return values, and more. Additionally, using descriptive variable names can help to make the code more self-explanatory. 

// Example of using inline comments to document variables
$userName = "John Doe"; // Variable to store the user's name
$userAge = 30; // Variable to store the user's age

/**
 * Class User
 * Represents a user in the system
 */
class User {
    /**
     * @var string $name The name of the user
     */
    public $name;

    /**
     * @var int $age The age of the user
     */
    public $age;
    
    /**
     * Constructor method to initialize the user object
     * @param string $name The name of the user
     * @param int $age The age of the user
     */
    public function __construct($name, $age) {
        $this->name = $name;
        $this->age = $age;
    }
}
