javascript - 有什么好的解决方案实现php和html的代码分离么
前端代码和php混合在一起,现在想实现分离,不用smarty这种模版引擎,还有其他什么方法么? 提交,修改,加载更多数据部分用了ajax,但是默认的数据读取还是用php的echo。

但事实上,模板引擎就是为了解决这问题而生的啊。第一下就否决了。
目前新的技术说是用基于js的模板引擎来生成Dom,或者angular js,由js来绑定数据到Dom。即PHP输出数据成js,js进行Dom生成。
一切的数据来源都用异步请求来获取
我知道的方案有两种
所有你需要的数据都通过ajax请求。后台提供接口。
使用模板渲染
我接触过的网站一般都是两种混合使用。因为一般网站都有大量复用的部分,因此需要使用静态模板,在服务端渲染成html。需要数据的地方,任然需要使用ajax请求。
当然听说现在已经有了比ajax请求更加高级的数据交互方案,不过我没用过
比较传统的方法
方法1.纯使用模板引擎
方法2.模板渲染和ajax混着用,ajax只用于异步处理数据
优点:逻辑清晰,简单
劣势:流量的浪费,服务端开销增大,维护的不便
比较现代的方法
前后端完全分离
前端只处理交互界面的逻辑(于是前端又分了很多 方法/框架 来进行页面逻辑的处理)
前端只在需要数据的时候通过 ajax/pjax 获取数据并填充需要的部分
你可以选择
所有操作均使用ajax,后端只提供json接口。这样就是angular那种做法。
查询操作渲染模板,其它操作使用ajax。这样是传统做法。
不推荐所有操作都渲染模板,体验很差。
RESTful。
PHP本来就是个模板引擎,你分离他干嘛呢?
楼主,PHP的模板引擎比较多,但主流的还是smarty,论效率论上手都不错啊,干嘛不用呢
如果走极端(你能重构整个项目),那也可以考虑纯前后端分离,用knockout angularjs这些js框架做前端,php只在后端做api。当然也要看你项目是否合适了,说白了,仅仅依靠原生php代码来做WEB,目前几乎很难看到吧
可以参考下淘宝UED的前后端分离系列文章:
http://ued.taobao.org/blog/?s=%E5%89%8D%E5%90%8E%E7%AB%AF%E5%88%86%E7%A6%BB
我是用angular来实现,基本步骤:
1、加载静态的页面框架;
2、通过ajax获取动态部分的内容;
3、通过ajax获取数据。
写了个directive标准化一下第2步:
HTML
<code><div dynamic-html="Page.html"></div></code>
JS
<code>app.directive('dynamicHtml', function($compile) { return { restrict: 'EA', replace: true, link: function(scope, ele, attrs) { scope.$watch(attrs.dynamicHtml, function(html) { if (html && html.length) { ele.html(html); $compile(ele.contents())(scope); } }); } }; });</code>
想实现分离,不用模板恐怕不行。要么用现成的模板引擎,要么自己实现一个。如果只是不喜欢smarty的语法的话,可以采用支持PHP原生语法的模板引擎,比如plates。
一直使用纯原生PHP

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
