    [1] => Array
        (
            [id] => 58
            [testo] => 
            [data] => 2013-06-03
            [orario] => 00:00:00
            [nome_files] => 20130603100647_da_installare.rtf
            [pubblicato] => 1
        )

    [2] => Array
        (
            [id] => 59
            [testo] => Demo
            [data] => 2013-06-03
            [orario] => 00:00:00
            [nome_files] => eye_drops_water_2.jpg
            [pubblicato] => 1

尝试 ksort 函数或 array-multisort

检查 php 文档： http: //php.net/manual/en/function.ksort.php http://php.net/manual/en/function.array-multisort.php
