Homephp教程PHP源码接口返回数据用xml好还是json理解

    现在移动端兴起,很多地方都要运用接口为它们传输数据,那么是用xml好还是用json好呢?个人觉得用json是不错的选择。我从以下几点分析一下:

1. xml标签要成对的书写,比如

XXXXXX,而json写法是{"name":"XXX","name":"XXX"},

所以很明显json更节约传输的容量。

2. json生成和解析数据都比较简单,以php为例,只需用一个json_encode函数就可以将一个数组转为json数据了,而xml生成过程相对会麻烦一点。

3. json扩展比较方便,解析速度也较快一点。

所以项目中没有特别的规定,还是用json比较好。

以上就是接口返回数据用xml好还是json理解的内容,更多相关内容请关注PHP中文网(www.php.cn)!

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
