I may be barking up a tree - however as far as I know you can nest all you want. FOr instance, this is perfectly valid and works:

PHP Code:

foreach($array1 as $key1=>$value1){
foreach($value1 as $key2=>$value2){
foreach($value2 as $key3=>$value3){
foreach($value3 as $key4=>$value4){
echo("er... shall I go on?");
 
}
}
} 
} 


glad to see the indent feature works in php blocks
