Getting data in a big array codeigniter

By default, arrays start with index 0. So 0 is the key of the first element in an array, 1 for the next element and so on.

In your code:

PHP Code:

$data['suggest'] = array(
'suggestedUser' => $data['suggested'][0]->suggestedUser,
'mutualFriend'  => $data['suggested'][0]->mutualFriends,
); 


you only put the first element [0] in the 'suggestedUser' and 'mutualFriend' elements. That's why you only get one user.
