PHP: Array of objects is empty when I come to retrieve one from the array
- by Tom
Good morning,
I am trying to load rows from a database and then create objects from them and add these objects to a private array.
Here are my classes:
<?php
include("databaseconnect.php");
class stationItem {
private $code = '';
private $description = '';
public function setCode($code ){
$this->code = $code;
}
public function getCode(){
return $this->code;
}
public function setDescription($description){
$this->description = $description;
}
public function getDescription(){
return $this->description;
}
}
class stationList {
private $stationListing;
function __construct() {
connect();
$stationListing = array();
$result = mysql_query('SELECT * FROM stations');
while ($row = mysql_fetch_assoc($result)) {
$station = new stationItem();
$station->setCode($row['code']);
$station->setDescription($row['description']);
array_push($stationListing, $station);
}
mysql_free_result($result);
}
public function getStation($index){
return $stationListing[$index];
}
}
?>
As you can see I am creating a stationItem object per database row (which for now has a code and description) and I then push these on to the end of my array which is held as a private variable in stationList.
This is code which creates this classes and attempts to access the properties on them:
$stations = new stationList();
$station = $stations->getStation(0);
echo $station->getCode();
I am finding that the sizeof($stationList) at the end of the constructor is 1 but then it is zero when we come to try to get an object from the array using the index. Therefore the error that I get is:
Fatal error: Call to a member function getCode() on a non-object
Please can someone explain to me why this is happening? I guess I am misunderstanding how object references work in PHP5.
