使用php构建复杂的JSON

我需要从PHP构建一些JSON。JSON的结构并不简单：

{ 

    "new" : {
        "checkpoints" : 
            [
                { 
                    "id" : "businessidea",
                    "name" : "business idea",
                    "purpose" : "Form a business idea", 
                    "customer" : 
                        { "questions" : 
                            [

                                { "questionid" : "id1", "questiontitle": "Evaluate size of the market, likely growth vectors and estimate addressable size.", "answers" :
                                  [
                                      {"answertext" : "an answer here", "answerlink": "", "answers": [
                                          {"answertext": "answer text here", "answerlink": "http://google.com"},
                                          {"answertext": "answer text here", "answerlink": "http://google.com"},
                                          {"answertext": "answer text here", "answerlink": "http://google.com"},
                                          {"answertext": "answer text here", "answerlink": "http://google.com"}
                                      ]},

                                          {"answertext": "answer text here", "answerlink": "http://google.com"},
                                          {"answertext": "answer text here", "answerlink": "http://google.com"},
                                          {"answertext": "answer text here", "answerlink": "http://google.com"}

                                  ]}
                            ]
                        },

实现这一目标的最佳方式是什么？我是通过使用大量字符串连接来构建这个json，还是可以使用PHP内置的json工具？

<?php echo json_encode($yourArray); ?>

我是否通过使用大量字符串连接来构建这个json

不可以。永远不要通过将字符串混合在一起来构建JSON

或者使用PHP内置的JSON工具是否可行

<?php echo json_encode($yourArray); ?>

对

用PHP构建数据结构。具体如何做取决于首先从何处获取数据

---

完成后，将其传递。

使用

json\u decode

，如果希望将其作为数组，则添加

true

作为第二个参数。

您从不使用字符串函数构建json

---

创建一个数组（或stdClass对象）并将其保存。

使用数组来构造数据，然后使用json_encode将其转换为json

除非您正在为一种不存在好的JSON序列化程序的语言编写JSON序列化程序，否则根本没有可以接受的理由这样做。有些解决问题的方法是错误的。（和边缘的情况，如“我们需要它昨天，没有时间升级PHP到远程现代的东西”，应该尖叫和适当尽快与黑客识别为黑客）。使用字符串创建JSON不是最好的方式，您将强制PHP对字符串求值，以了解数据的类型，这是一个键，这就是数据。使用数组不需要进行评估，因为数组内部知道valuesOk的数据类型，如何在php中构建数据结构？我正在从数据库调用中获取数据。通过创建和分配

Array

s。
