Little problem in classes

[Anon]

Hi I need to increment values in classes.

without it is simple but how can I do it in this case?->

<?
class ForwardBackward
{
function move($step)
{
$this->value=$this->value+$step;
}
function place()
{
echo "I am standig: $this->value<br>";
echo "<A href='$PHP_SELF?go=-1'> << </A> &nbsp; <A href='$PHP_SELF ?go=1'> >> </a>";
}
}
$a= new ForwardBackward;
$a->move($go);
$a->place();
?>

I need that when I hitting >> link $this->value increments in function move and shows correct values in function place() like 1, 2, 3, 4, etc...

thanx....

<?
class ForwardBackward
{
var $value;
function move($go) {
$this->value=$go;
}
function place()
{
echo "I am standig: $this->value<br>";
echo "<A href='$PHP_SELF?go=".($this->value-1)."'> << </A> <A href='$PHP_SELF ?go=".($this->value+1)."'> >> </a>";
}
}
$a= new ForwardBackward;
$a->move($go);
$a->place();
?>

The problem with your code is that the class can't remember how it was last time the page was viewed. by simply changing the links to their absolute values instead of relative changes to the supposedly stored value, it moves along nicely.
