Have you tried [`uasort()`](http://php.net/uasort)? – Ja͢ck Feb 05 '14 at 06:35 — Ja͢ck, Feb 05 '14 at 06:35

Using sort:

sort($input_array, SORT_NATURAL | SORT_FLAG_CASE)

Note that this requires PHP 5.4.0+ for SORT_NATURAL AND SORT_FLAG_CASE use. See sort manual for details.

This doesn't sort the array properly. – Ja͢ck Feb 05 '14 at 06:50
@Jack, please define "properly". This does require `PHP 5.4` for `SORT_NATURAL` AND `SORT_FLAG_CASE` as sort_flags parameter. Updating answer. – vee Feb 05 '14 at 06:52
For one, each element in the array is not a string, but an array. I suppose you didn't test it? – Ja͢ck Feb 05 '14 at 12:10

Use uasort() with strcasecmp() for the comparison:

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