我可以通過<br>標籤提高「json_encode」結果的可讀性嗎？

Question

我只是迴應我的聲明結果作爲JSON對象。但功能json_encode（）推出的一切都變成這樣一行：

{"0":{"username":"Olli"},"1":{"username":"Heiner"},"2":{"username":"Rolf"},"success":true,"rowcount":3"0":{"username":"Olli"},"1":{"username":"Heiner"},"2":{"username":"Rolf"},"success":true,"rowcount":3"0":{"username":"Olli"},"1":{"username":"Heiner"},"2":{"username":"Rolf"},"success":true,"rowcount":3"0":{"username":"Olli"},"1":{"username":"Heiner"},"2":{"username":"Rolf"},"success":true,"rowcount":3"0":{"username":"Olli"},"1":{"username":"Heiner"},"2":{"username":"Rolf"},"success":true,"rowcount":3"0":{"username":"Olli"},"1":{"username":"Heiner"},"2":{"username":"Rolf"},"success":true,"rowcount":3"0":{"username":"Olli"},"1":{"username":"Heiner"},"2":{"username":"Rolf"},"success":true,"rowcount":3"0":{"username":"Olli"},"1":{"username":"Heiner"},"2":{"username":"Rolf"},"success":true,"rowcount":3"0":{"username":"Olli"},"1":{"username":"Heiner"},"2":{"username":"Rolf"},"success":true,"rowcount":3"0":{"username":"Olli"},"1":{"username":"Heiner"},"2":{"username":"Rolf"},"success":true,"rowcount":3"0":{"username":"Olli"},"1":{"username":"Heiner"},"2":{"username":"Rolf"},"success":true,"rowcount":3} 

現在想象一下，一個JSONObject與多個條目百名。

有沒有辦法添加一些<br>標籤或製表位來提高可讀性？這應該只是爲了測試目的而不是進一步解析。

結帳JSON_PRETTY_PRINT標誌。

echo json_encode([[[[[[['a'=>'b']]]]]]],JSON_PRETTY_PRINT); 

輸出：

[ 
    [ 
     [ 
      [ 
       [ 
        [ 
         { 
          "a": "b" 
         } 
        ] 
       ] 
      ] 
     ] 
    ] 
]
