OOP in PHP - object array iteration - php

Question

I am trying to iterate through array of objects in PHP, but I can't figure it out. This is my code:
require_once("databaseConnect.php");
require_once("class/Ticket.php");
function showAll(){
$sql = "SELECT * FROM Ticket WHERE Status='1'";
$p = mysql_query($sql);
while ($row = mysql_fetch_object($p)){
$t = new Ticket($row->IDTicket, $row->IDUser, $row->TotalOdd, $row->PlacedBet, $row->PossibleWin, $row->Status, $row->Won, $row->Time);
$nizTiketa[] = $t;
}
return $nizTiketa;
}
$niz = showAll();
for ($i; $i<count($niz); $i++){
echo $niz[$i]->getIDTicket()."<br/>";
}
and this is class Ticket:
class Ticket {
private $IDTicket;
private $IDUser;
private $TotalOdd;
private $PlacedBet;
private $PossibleWin;
private $Status;
private $Won;
private $Time;
function Ticket($idTicket, $idUser, $totalOdd, $placedBet, $possibleWin, $status, $won, $time) {
$this->IDTicket = $idTicket;
$this->IDUser = $idUser;
$this->TotalOdd = $totalOdd;
$this->PlacedBet = $placedBet;
$this->PossibleWin = $possibleWin;
$this->Status = $status;
$this->Won = $won;
$this->Time = $time;
}
function getIDTicket(){
return $this->IDTicket;
}
function setIDTicket($idTicket){
$this->IDTicket = $idTicket;
}
.
.
.
I got error Call to a member function getIDTicket() on a non-object
How should it be done?

Couple of things I'd do here for sanity...
As mentioned by Joe, initialise your array before adding elements, eg
function showAll() {
$nizTiketa = array();
// ...
Either initialise your iteration counter $i to zero
for ($i = 0, $count = count($niz); $i < $count; $i++)
or more simply, use foreach
foreach ($niz as $ticket) {
echo $ticket->getIDTicket(), "<br/>";
}
