oop.php

<?php

class Member
{
    private $email;

    public function getEmail(): string
    {
        return $this->email;
    }

    private $password;

    public function authenticate(string $password): bool
    {

    {
        $this->email = $email;
        $this->password = $password;
    }
}

// --

$member = new Member('[email protected]', 'some password');

// pake password yg bener
$result = $member->authenticate('some password');

// pake password yg salah
$result = $member->authenticate('wrong password');
echo 'Member ', $member->getEmail(), ' is ', ($result ? 'authenticated' : 'not authenticated'), PHP_EOL;

prosedural.php
