Arrays into classes

[ghornet]

Hello everyone i am trying to make my first class I am trying to pass a array into the constructor but it is not working correctly

$questionnumbers[0] = "1";
$questionnumbers[1] = "3";

$newtf = new tf("$questionnumbers", "$db");

//this class is to hold all of the true false questions from the db
class tf
{
var $i;
function tf($questionnumbers, $db)
{
while($i<count($questionnumbers))
{
echo $questionnumbers[$i];
$i++;
}
}

I would expect to see 1 and 3 but all I see is A on the screen. Whats the trick??
Thanks

why are you putting your vars in quotes?

when you do this it means you're passing a STRING, not an array, and the vars are simply expanded into their string representations. For arrays, it's 'Array'.

Since $i is a class variable you probably meant: $this->i. You also never intialized $i to 0 before you went into the while loop.
