如何根據特定元素的值有條件地刪除子陣列？

    4 => array:23 [▶] 
    5 => array:23 [▶] 
    6 => array:23 [▶] 
    7 => array:23 [▶] 
    8 => array:23 [▶] 
    9 => array:23 [▶] 
    10 => array:23 [▶] 
    11 => array:23 [▶] 
    12 => array:23 [▶] 
]

我想刪除具有account_id == null的那些陣列。

我試圖對其進行解碼：

$vcpes = json_decode (json_encode ($vcpes), FALSE);

，並檢查它：

foreach($vcpes as $vcpe){ 
    if($vcpe->account_id == null){ 
     //delete it 
    }else{ 
     //don't delete it 
    } 
}

我希望有人可以給我一點提示這一點。

'如果（$ vcpe [ 'ACCOUNT_ID'] == NULL）'' –

$結果= array_filter評論（$ originalArray，function（$ value）{return $ value ['account_id']！== null;}）;' –

->用於獲取對象的屬性。要從數組中獲取值，請使用$array['key']表示法。

foreach($vcpes as $i => $vcpe){ 
    if ($vcpe['account_id'] === null) { 
     unset($vcpes[$i]); 
    } 
}

我解碼它，因此我使用箭頭。抱歉更新我的帖子太慢了。但是你正在回答我的問題。 :) – ihue

我喜歡'unset（）'建議。 – ihue

你可以試試這個方法，或者只是使用array_filter()由@馬克·貝克

$finalArray = []; 
foreach($vcpes as $vcpe){ 
    if($vcpe->account_id != null){ 
     $finalArray[] = $vcpe; 
    } 
} 

print '<pre>'; 
print_r($finalArray); 
print '</pre>';

好的建議，我會把它添加到我的PHP工具箱中。感謝Sunny。 – ihue
