【问题描述】：

我只是将我的语句结果作为 JSON-Object 来回显。但是函数 json_encode() 将所有内容都放在一行中：

"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

现在想象一个有数百个条目的 JSON 对象。

有没有办法添加一些<br> 标签或制表位来提高可读性？这应该仅用于测试目的，而不是用于进一步解析。

【问题讨论】：

为什么不改为json_decode呢？

@tilz0R: ...然后炸毁试图使用 JSON 的另一端。

【参考方案1】：

查看JSON_PRETTY_PRINT 标志。

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

输出：

[
    [
        [
            [
                [
                    [
                        
                            "a": "b"
                        
                    ]
                ]
            ]
        ]
    ]
]

@T.J.Crowder 恕我直言，先生，我怀疑你从来没有自己做这件事并没有赢得 570k 代表（例如：***.com/questions/39611979/…）。考虑到现在很多答案，比如这个答案，都必须非常很快地写出来。很容易忽略重复检查。
