php - How to store values from foreach loop into an array?

Question

Need to store values from foreach loop into an array, need help doing that.

The code below does not work, only stores the last value, tried $items .= ..., but that is not doing the trick either, any help will be appreciated.

foreach($group_membership as $i => $username) {
    $items = array($username);
}

print_r($items);

Answer 1

Declare the $items array outside the loop and use $items[] to add items to the array:

$items = array();
foreach($group_membership as $username) {
 $items[] = $username;
}

print_r($items);
