Personally, your doing it all wrong...
Use foreach, since you've already got your key and your item defined...
and all you need is to generate generic varibles... the only way to do
that is to use this function ${'varname'};
<?php
$array = array('0' => 'a', '1' => 'b', '2' =>'c', '3' =>'d', '4'=>'e');
foreach ($array as $key => $item) {
${'pos' . $key} = $item;
}
echo $pos3; // $pos3 should equal 'd'
die();
?>
Don't forget... read the manual before asking questions...
