I am using this to sort according to last name:
usort($fb_friends['data'], "custom_sort"); function custom_sort($a,$b) { return $a['last_name']>$b['last_name']; } foreach($fb_friends['data'] as $friend) { echo '<br>'; echo $friend['name']; }
But – when in last name is accent, e.g. Šiko, Áron, etc, these names are at the end. How can I sort it properly?

Use multi-byte string functions. There is a function called strcoll
which seems to suit your needs.

EDIT: added Peter’s working code, below
setlocale(LC_COLLATE, 'sk_SK.utf8'); usort($fb_friends['data'], 'custom_sort'); function custom_sort($a, $b) { return strcoll ($a['last_name'], $b['last_name']); } foreach ($fb_friends['data'] as $friend) { echo '<br>'; echo $friend['name']; }
