Are there any specific PHP best practices or guidelines for transitioning from VB and Delphi to PHP programming?

When transitioning from VB and Delphi to PHP programming, it is important to familiarize yourself with PHP best practices and guidelines to ensure a smooth transition. Some key practices to keep in mind include using object-oriented programming, following naming conventions, utilizing built-in functions and libraries, and properly handling errors.

// Example PHP code snippet demonstrating the use of object-oriented programming
class User {
    private $username;
    
    public function setUsername($username) {
        $this->username = $username;
    }
    
    public function getUsername() {
        return $this->username;
    }
}

$user = new User();
$user->setUsername('john_doe');
echo $user->getUsername();
