Question

for($i=0;$i<5;$i++){
    $an_array = array();
}

Please let know if the array definition will also the clear the array after the first iteration.

Answer 1

Yeh the array will be cleared each time.
You could create unique arrays each time with the follow if thats what you require.

 for($i=0;$i<5;$i++){
    $an_array[$i] = array();
 }
