Question

我有這樣的陣列

Array (
    [0] => Array 
     (
      [id] => 61 
      [testo] => articolo di maggio 
      [data] => 2013-05-03

      [nome_files] => fabmad_1920x1200.jpg 
      [pubblicato] => 1 
     ) 

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

    [2] => Array 
     (

      [testo] => Demo 
      [data] => 2013-06-03 
      [orario] => 00:00:00 
      [nome_files] => eye_drops_water_2.jpg

嘗試ksort函數或陣列multisort

檢查PHP文檔：http://php.net/manual/en/function.ksort.php http://php.net/manual/en/function.array-multisort.php
