[Resolved] Array - displaying every second, third item

[ph3n0m]

I have an array

$total = array("0","1","2","3","4","5","6","7");

or something similiar, and depending on various elements, it grows larger or smaller, etc

What I need to be able to do is display every second item in the array

i.e., using the array above, I would love to be able to output

1,3,5,7

However because the array can grow exponentially I cannot do it manually

Does anyone have any ideas - been googling with no joy

nevermind - gah why do my best ideas come after posting

The solution I used was this

$total = array("0","1","2","3","4","5","6","7");
$totaller = count($total);
$i = 2;
$increment = 3;

while ($i < $totaller){

echo $total[$i];
$i = $i + $increment;}

You might want to look up the [man]for[/man] statement. It would simplify your code.
