            [email] => [email protected]
            [group] => 
            [href] => http://localhost/teradasys/index.php/users/user/user_info?&user_id=5
        )

I want to sort by name how can I do it?

Answer 1

uasort() function is what you're looking for.

uasort($data, function($a, $b) { return strcasecmp($a['name'], $b['name']); });

You should take a look on usort() and uksort() doc for examples of how user-defined comparison functions works.
