使用php构建复杂的JSON

Question

我需要从PHP构建一些JSON。在JSON的结构是小于琐碎：

{ 

    "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"} 
             ]},

什么是实现这一目标的最佳途径？我是否通过使用大量字符串连接来构建这个json的路线，或者使用内置JSON工具的PHP是否可行？

Answer 1

难道我用大量的字符串连接的

号切勿串糖化共筑JSON下井建设这个JSON的路线。

还是可行的使用PHP的内置JSON工具？

是。

在PHP中构建数据结构。具体的做法取决于你从哪里获取数据。

完成后，通过json_encode。

Answer 2

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

Answer 3

使用json_decode，将true作为第二个参数添加，如果您希望它作为数组。

Answer 4

你从来没有使用字符串函数来构建JSON！

创建一个数组（或stdClass对象）和json_encode()它。

Answer 5

使用数组来构造数据，然后使用json_encode将其转换为JSON。 JSON Encode documentation
