At what point does one transition from being a PHP beginner to a PHP intermediate or expert?

Transitioning from being a PHP beginner to an intermediate or expert level typically occurs when one has a deep understanding of PHP syntax, can write complex algorithms and logic, utilize advanced features like object-oriented programming, and demonstrate proficiency in debugging and optimizing code. This transition is marked by the ability to tackle more challenging projects and solve problems efficiently using PHP.

// Example PHP code snippet demonstrating intermediate-level proficiency

class User {
    private $name;
    
    public function __construct($name) {
        $this->name = $name;
    }
    
    public function greet() {
        return "Hello, my name is " . $this->name;
    }
}

$user1 = new User("John");
echo $user1->greet(); // Output: Hello, my name is John
