PHP指數數組JSON

Question

尋找一些幫助。不知道這個問題的最佳途徑...... 我推着一個新的參考到一個數組，但「真實」價值被插入帶引號的，這失敗了我的json格式。

while($row = mysqli_fetch_assoc($res)) { 
    if($row['id']=="2"){ 
    $row['children']= 'true'; 
    } 
    $data[] = $row; 
} 
echo json_encode($data); 

輸出

[{"id":"2","name":"john","text":"john","parent_id":"0","children":"true"}] 

當我需要......

{"id":"2","name":"john","text":"john","parent_id":"0","children":true}] 

我會如何去除qoutes或先正確插入。??

如果你想「孩子」是布爾然後將其設置爲布爾值。

while($row = mysqli_fetch_assoc($res)) { if($row['id']=="2"){ $row['children'] = true; } $data[] = $row; } echo json_encode($data);
