How important is it to properly document PHP classes for future reference?

Properly documenting PHP classes is crucial for future reference as it helps other developers understand the purpose and functionality of the class without having to dig through the code. This documentation can include information such as class description, properties, methods, parameters, return types, and examples of usage. By maintaining clear and comprehensive documentation, developers can easily navigate and utilize PHP classes in their projects.

/**
 * Class User
 * Represents a user in the system.
 */
class User {
    /**
     * @var string The user's name.
     */
    private $name;

    /**
     * Sets the user's name.
     * 
     * @param string $name The user's name.
     */
    public function setName($name) {
        $this->name = $name;
    }

    /**
     * Gets the user's name.
     * 
     * @return string The user's name.
     */
    public function getName() {
        return $this->name;
    }
}
