php框架 - PHP里如果是纯PHP程序,不嵌套HTML性能会高些吗?

好了,问题如题,如果PHP程序不嵌套HTML代码,就是一个纯的PHP程序,只做数据库的数据处理或者是图片的处理,不嵌套html代码,执行效率是否会高很多?

在此做一下说明:

<code>可以,渲染我全部交给前端来处理,后端php只提供服务,通过JSON数据传输。
</code>
Copy after login
Copy after login

<code>在此我对自己的这个疑问做一下回答:我亲自做了测试了,php如果仅仅是纯操作,不用来解析MVC,效率是会高些,但并没想象的那么高,不会有快到两三倍的说法。但是前后端完全分离,对开发是特别有好处的。</code>

你所谓的HTML渲染其实也是php把html模板文件或文本字符串读进去处理完再输出出来而已。
你所说的“只做数据库的数据处理或者是图片的处理,不嵌套html代码”可能就是把这一步省略掉了。既然有省略掉的步骤,那效率肯定会变高。

当然你是把组装html的步骤替换成组装json了,你要确保这一步性能不比之前差。

而如果是图片数据的话,设计不好的话会多一次http请求,设计的不好的话可能速度会变差。

不用渲染HTML, 性能当然会高一点.
但是你确定"不渲染HTML"真的可以吗?

题主是想做前后端完全分离?如果是的话,可以对php端服务器进行优化来提高效率。

不会高,php本身就是c写的一种模板 ,最大的优势就在于嵌套html 纯cpu计算,任务调度,io处理都是php的劣势

问题是渲染页面所需时间长还是数据库处理时间长

这...这不就是传说中的MVC设计模式嘛!
控制层模型层视图层分离。控制器相当于接口,根据视图层的数据调取相应的模型层进行数据处理!
模型层负责业务逻辑运算控制层负责分配任务和向视图层输出数据,再加上opcode缓存、memcacheredis缓存,我的天呐!要上天了喵~
