How do I make a property private in a class? : <pre><code>class makeAccount {
public $username;
public function __construct ($username,$password) {
    $this-&gt;username = $username;
}
public function password($password) {
    if(isset($password)) {
       $this-&gt;password = $password;
       return;
    }
  }
}

$user_1 = new makeAccount("abc123","12345");
print $user_1-&gt;password("12345");
</code></pre>

<p>I am new to php. I am just wondering how to make a private property. I want to have a password property that is private. Is there something wrong with my code?</p>
