[RESOLVED] Casting objects that are in an array

[nubs]

Hello. If I have the code which adds Car objects to an array:

	for ( $counter = 0; $counter <= 10; $counter ++) {
		$car= new CAR();
		$car ->setRegistration("Registration" . $counter);
		$carArray[$counter] = $car;
	}

How do I retrieve them and use them as car objects ? I would expect that to print the registrations, it would be something like:

for ($i =0;$i < count($carArray);$i++){
	echo ($carArray[$i] -> getRegistartion();); 

But that produces an error of:

'Call to a member function getThreadName() on a non-object in...'

I expect I have to type cast the item in the array. But how? I expect something like:

$car = (Car) $carArray[$i];

But that fails too. Any help would be appreciated.

Thanks,

Matt.

It worked OK for me once I fixed the spelling of getRegistration.

<?php
class CAR
{
   var $registration;
   function setRegistration($num)
   {
      $this->registration = $num;
   }
   function getRegistration()
   {
      return($this->registration);
   }
}

for ($counter = 0; $counter <= 10; $counter ++) {
   $car= new CAR();
   $car ->setRegistration("Registration" . $counter);
   $carArray[$counter] = $car;
}

for ($i =0; $i < count($carArray); $i++)
{
   echo $carArray[$i]->getRegistration() . "<br>\n";
}

Output:

Registration0
Registration1
Registration2
Registration3
Registration4
Registration5
Registration6
Registration7
Registration8
Registration9
Registration10

Hello. Thankyou very much for this. I see what my problem is.

The array was being returned from a function. So I had:

$carArray[] = CarFactory -> getCars();

However that is adding the returned array to be the first item of the $carArray, not setting it to be the array itself. So what I really need is simply:

$carArray = CarFactory -> getCars();

And that works. I'm getting the hang of this 🙂 Thankyou very much for your help.
