Tried, gives the same result with one element :(
What's working:
$cats = array( array( 'id' => 1 ) );
while ( $c = array_shift($cats) ) {
echo $c['id'];
if ( $c['id'] < 5 ) {
$c['id']++;
$cats[] = $c;
}
}
But this is 'while' and it pops all elements from the array...
Cheers,
Tamas

Or maybe he tried to do the following?
<?php
foreach ( $cats as&$c ) {
echo $c['id'];
if ($c['id']< 5) {
$cats[] = array('id' => ($c['id'] + 1));
}
}
?>
