如何重組陣列在PHP

Question

我有PHP數組這樣

[ 
['name'=>'john0', 'order' => '1'], 
['name'=>'john1', 'order' => '2'], 
['name'=>'john2', 'order' => '2'], 
['name'=>'john3', 'order' => '3'], 
['name'=>'john4', 'order' => '3'], 
['name'=>'john5', 'order' => '4'], 
['name'=>'john6'], 
['name'=>'john7', 'order' => '5'], 
] 

我想從ASC

以下

1. 排序順序。如果順序是不是有那麼元素應該追加到最後
2. 如果訂單相同，那麼它們應該組合在一起排列在一起

結果應該是

['john0',['john1','john2'],['john3','john4'],'john5','john7','john6'] 

Answer 1

你可以做如下

$aResultArray = array(); 
$aTempWithoutorder = array(); 
foreach($aArray AS $array) 
{ 
    if(isset($array['order']) 
    $aResultArray[$array['order']][] = $array['name']; 
    else 
    $aTempWithoutorder = $array; 
} 
ksort($aResultArray); 
$aRearrange = array(); 
foreach($aResultArray AS $iOrder=>$name) 
{ 
    $aRearrange[] = $name; 
} 
$aFinalArray = $aRearrange + $aTempWithoutorder; 

$aFinalArray will have order
