Have a strange problem with methods..
if i use function to return some array and doing 2-level nested foreach(),
for example
function x(){
return array(1, 2,3);
}
foreach(x() as $key){
echo $key .br;
foreach(x() as $key2){
echo nbsp;nbsp; . $key2 . br;
}
}

yes there is difference in creation returning array.. but i talk about other

method or function
2. here we don't return reference to the same array.
3. foreach - as i have read in most sources Makes a copy of given
3 matches
