[Solved] Error in the exercise of oop [closed]

Question

It is because there is no constructor in the Conta class.

Because, in the child class ContaPoupanca, you called the constructor of the parent class which is Conta like this:

parent::__construct($Agencia, $Codigo, $DataCriacao, $Titular, $Senha, $Saldo);

Therefore, to make this work, the parent class Conta should have a constructor like this:

public function __construct($Agencia, $Codigo, $DataCriacao, $Titular, $Senha, $Saldo) {
    // Do what you need to do here.
}

On a side note apart from this question, you haven’t defined the functions with an encapsulation keyword. That is either “public”, “private” or “protected”.
