And that's exactly how I did it :)
Since 'for' is traditionally pre-testing with excetuting the condition prior looping
it's working well :)
Thanks for all the help!
Cheers,

Just use count($arr) in your for-header, as it get's executed again
for each loop.
<?php
$arr = array(array('id'=>1), array('id'=>2));
for($i=0;$i<count($arr);$i++) {
echo $arr[$i]['id'];
if($i < 6) {
$arr[] = array('id' => $arr[$i]['id']+1);
}
}
?>
