Php “我能改进吗？”；json_encode"；结果可读性与<；br>；标签？

我只是将我的语句结果作为JSON对象进行回显。但是函数json_encode（）将所有内容放在一行中，如下所示：

{"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}

现在想象一个JSONobject，它还有上百个条目

有没有办法添加一些标签或制表位来提高可读性？这仅用于测试目的，不用于进一步分析。
