How can I modify the PHP loop in order to apply it to every group?

edit

To modify the PHP loop to apply it to every group, you can use nested loops. Here's an example:

$groups = array(
  array('name' => 'Group A', 'members' => array('John', 'Paul', 'George')),
  array('name' => 'Group B', 'members' => array('Ringo', 'George', 'Fred')),
  array('name' => 'Group C', 'members' => array('Mary', 'Jane', 'Bob')),
);

foreach ($groups as $group) {
  echo $group['name'] . ':<br>';

  foreach ($group['members'] as $member) {
    echo '- ' . $member . '<br>';
  }

  echo '<br>';
}

This code will loop through each group in the $groups array, and for each group it will output the group name and the names of its members. The output will look something like this:

Group A:
- John
- Paul
- George

Group B:
- Ringo
- George
- Fred

Group C:
- Mary
- Jane
- Bob
