How can a beginner in PHP programming effectively incorporate object-oriented programming principles into their code, especially when dealing with complex tasks like bank account management?

To effectively incorporate object-oriented programming principles into PHP code for tasks like bank account management, beginners can start by defining classes for objects like BankAccount with properties and methods to handle transactions and balances. Encapsulation, inheritance, and polymorphism can be used to organize and extend the code efficiently. Additionally, beginners can utilize access modifiers like public, private, and protected to control the visibility and accessibility of class members. 

class BankAccount {
    private $balance;

    public function __construct($initialBalance) {
        $this->balance = $initialBalance;
    }

    public function deposit($amount) {
        $this->balance += $amount;
    }

    public function withdraw($amount) {
        if ($amount <= $this->balance) {
            $this->balance -= $amount;
        } else {
            echo "Insufficient funds";
        }
    }

    public function getBalance() {
        return $this->balance;
    }
}

$account = new BankAccount(1000);
$account->deposit(500);
$account->withdraw(200);
echo "Current balance: " . $account->getBalance();
