关于php：我可以使用＆lt; br＆gt;改进“json_encode”结果的可读性


Can i improve “json_encode” results readability with <br> tags?

本问题已经有最佳答案，请猛点这里访问。

我只是将我的语句结果作为JSON对象进行重复。但是函数json_encode()将所有内容都放到一行中，如下所示：

1
{"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有更多的条目。

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

签出JSON_PRETTY_PRINT标志。

1
echo json_encode([[[[[[['a'=>'b']]]]]]],JSON_PRETTY_PRINT);

输出：
