Problem when printing specific array data - php

Question

I'm working with a player class, the code prints a form with name, lastname and location fields that have to be filled in to add a new player.
But I have a problem when printing the players since I only print the names of the players, when I try to print the data separately (name, lastname and location) I do not print anything.
session_start();
class Player {
private $players;
private $name;
private $lastname;
private $location;
public function __construct($name,$lastname,$location)
{
$this->name = $name;
$this->lastname = $lastname;
$this->location = $location;
$this->players = array();
}
public function getName()
{
return $this->name;
}
public function getLastname()
{
return $this->lastname;
}
public function getLocation()
{
return $this->location;
}
public function addPlayer($onePlayer)
{
$this->players[] = $onePlayer;
return $this;
}
public function printPlayers()
{
foreach($this->players as $player){
// just show the name¿?.
echo $player.'<br />';
// The problem is here.
/*echo $player['name'].'<br />';
echo $player['lastname'].'<br />';
echo $player['location'].'<br />';*/
}
}
public function __toString()
{
return $this->name;
return $this->lastname;
return $this->location;
}
}
function printForm()
{
echo '<FORM METHOD="POST" style="text-align: center; margin-top: 73px;">
<h2>Add Players</h2>
<label>Add the name : </label><INPUT class="form" TYPE = "text" NAME = "name"> <br>
<label>Add the lastname : </label><INPUT class="form" TYPE = "text" NAME = "lastname"> <br>
<label>Add the location : </label><INPUT class="form" TYPE = "text" NAME = "location"> <br><br>
<INPUT class="form" TYPE = "submit" VALUE = "add" name="action">
<INPUT class="form" TYPE = "submit" VALUE = "list" name="action">
</ FORM>';
}
// Load the player data of the session and if it does not exist create a new player.
function loadData()
{
return isset($_SESSION['player']) ? $_SESSION['player'] : new Player();
}
// Save the player's data in the session.
function saveData($player)
{
$_SESSION['player'] = $player;
}
printForm();
$player = loadData();
if(isset($_POST['action']))
{
switch($_POST['action'])
{
case 'add':
$player->addPlayer(new Player($_POST['name'],$_POST['lastname'],$_POST['location']));
saveData($player);
break;
case 'list':
echo '<hr />';
$player->printPlayers();
break;
}
}

It looks like in the problematic part you're trying to access private properties using array syntax. That won't work for a couple of reasons
The properties aren't accessible there because they're defined as private
You can't get them with array syntax. If they weren't private you'd need to use $player->name.
But fortunately you have also written some getters, so you should be able to use those instead, like this:
echo $player->getName();
