我的結果集來自一組/數查詢:有什麼辦法來檢查一個鍵是否存在於PHP中的嵌套數組中?
SELECT m.type, COUNT(m.type)
FROM sent_message m
WHERE m.user_id = :user_id
AND (m.sent_at >= :start_date OR m.sent_at <= :end_date)
GROUP BY m.type
而且它在 數組嵌套到另一個數組形式:
array (size=2)
0 =>
array (size=2)
'type' => string 'sms' (length=3)
'count' => string '1' (length=1)
1 =>
array (size=2)
'type' => string 'email' (length=5)
'count' => string '9' (length=1)
有沒有什麼辦法,如果能夠容易地檢查給定type
索引存在沒有循環?爲了避免這種情況:
$resultSet = $repository->getAllCount(); // Returns the nested array
$viewBag = array('sent_sms_count' => 0, 'sent_email_count' => 0); // Init
foreach($resultSet as $result) :
if('sms' == strtolower($result['type'])
$viewBag['sent_sms_count'] = $result['count'];
if('email' == strtolower($result['type'])
$viewBag['sent_email_count'] = $result['count'];
endforeach;
