PHP數組Ascending排序

Question

我和數組，我想按[sys_title]鍵索引升序排列這個數組。我該怎麼辦？

[0] => Array 
(
    [sys_id] => 9 
    [sys_title] => Checklist 
    [sys_home] => /cp/system/chl/ 
) 

[1] => Array 
(
    [sys_id] => 8 
    [sys_title] => Bakery Ordering System 
    [sys_home] => /cp/system/bos/ 
) 

預期結果應該是這樣的：

[0] => Array 
(
    [sys_id] => 8 
    [sys_title] => Bakery Ordering System 
    [sys_home] => /cp/system/bos/ 
) 

[1] => Array 
(
    [sys_id] => 9 
    [sys_title] => Checklist 
    [sys_home] => /cp/system/chl/ 
) 

Answer 1

你可以試試這段代碼：

usort($data,function($a,$b){ 
    return strcmp($a['sys_title'],$b['sys_title']); 
}); 

print_r($data); 

Answer 2

假設你的數組名是$一則：

$tmp = Array(); 
foreach($a as &$ma) { 
    $tmp[] = &$ma["sys_title"]; 
    array_multisort($tmp, $a); 
} 

結果將是

Array 
(
    [0] => Array 
     (
      [sys_id] => 8 
      [sys_title] => Bakery Ordering System 
      [sys_home] => /cp/system/bos/ 
     ) 

    [1] => Array 
     (
      [sys_id] => 9 
      [sys_title] => Checklist 
      [sys_home] => /cp/system/chl/ 
     ) 

)
