Learning Philosophy

Traditional tutorials tell you how things work. DALT.PHP makes you discover it by:

Reading a concept explanation
Encountering a broken implementation
Debugging and fixing the issue
Understanding through hands-on practice

This "learn by debugging" approach creates deeper understanding than passive reading.

Quick Example

// Challenge: Why does login always fail?
public function attempt($email, $password) {
    $user = $this->findUser($email);
    
    // Bug: Plain text comparison!
    if ($user && $password == $user['password']) {
        return true;
    }
    return false;
}
