爲什麼我的JSON數組在PHP中無法在我的Android應用程序中正確打印？

Question

在我的PHP文件我有代碼包括：

while ($row = $result->fetch_assoc()) { 

    //make an array called $results 
    $results = array(); 

    $results[] = array(
    'contact_phonenumber' => $row['username'], 
     ); 


    $json2 = json_encode($results); 
    //this is the response which we want in the Android app 
    echo $json2; 

而在我的Android應用程序，我有：

public void onResponse(String response) { 
    //print the JSON Array from the php file 
    System.out.println("the jsonarray is : " + response; 

的response當我打印，我得到的格式爲：

[{"contact_phonenumber":"+11111"}][{"contact_phonenumber":"+22222"}][{"contact_phonenumber":"+33333"}][{"contact_phonenumber":"+44444"}][{"contact_phonenumber":"+55555"}] 

但不應該是格式？ ：

[{"contact_phonenumber":"+11111"}, {"contact_phonenumber":"+22222"},{"contact_phonenumber":"+33333"}, {"contact_phonenumber":"+44444"},{"contact_phonenumber":"+55555"}] 

我該如何實現這個目標？

試試這個：

$result = []; 
while ($row = $result->fetch_assoc()) { 
    array_push(['contact_phonenumber' => $row['username']], $result); 
} 
$json2 = json_encode($result); 
//this is the response which we want in the Android app 
echo $json2;
