Why use CJSON encode when we have json

I am building an API for a website using Yii. I know that there is a utility class called CJson and has a function called encode. As far as I know there are additional parameters that can be customized in the native json_encode function like the JSON_NUMERIC_CHECK which is really useful. It creates { "id": 17 } instead of Yii's CJSON encode which makes the '17' a string. {

为什么在使用json时使用CJSON编码?

我正在为使用Yii的网站构建一个API。 我知道有一个名为CJson的实用程序类,并且有一个名为encode的函数。 据我所知,可以在本地json_encode函数中定制其他参数,如JSON_NUMERIC_CHECK,这非常有用。 它创建 { "id": 17 } 而不是Yii的CJSON编码,它使'17'成为一个字符串。 { "id": "17" } 所以我的问题是,是否有任何理由我应该使用CJSON编码,而不是内置的PHP函数json_encode? 只有我能想到最低的PHP

JSON和JSONP有什么区别?

可能重复: 请解释JSONP 例如在jQuery文档中,我发现提到了JSON和JSONP。 究竟有什么区别? 我怎么看到哪个是哪个? 哪一个应该用于什么? PHP函数json_encode是什么产生的? JSON是一种简单的数据格式。 JSONP是一种将这种格式与跨域Ajax请求结合使用,同时不会受到同源策略问题影响的方法。 基本上,这个想法是,不是使用ajax来请求JSON编码的数据,而是向页面添加一个脚本标记,将该数据加载为JavaScript脚本,

How to use the CSV MIME

In a web application I am working on, the user can click on a link to a CSV file. There is no header set for the mime-type, so the browser just renders it as text. I would like for this file to be sent as a .csv file, so the user can directly open it with calc, excel, gnumeric, etc. header('Content-Type: text/csv'); echo "cell 1, cell 2"; This code works as expected on my computer (Isn't

在我正在处理的Web应用程序中,用户可以点击指向CSV文件的链接。 没有为MIME类型设置标题,所以浏览器只是将它呈现为文本。 我想将这个文件作为一个.csv文件发送,所以用户可以直接用calc,excel,gnumeric等打开它。 header('Content-Type: text/csv'); echo "cell 1, cell 2"; 此代码在我的计算机上按预期工作(是不是它总是如此?),但在另一台计算机上不起作用。 我的浏览器是FF 3.0.1(在Linux上)的夜间版本。 它
