帮忙看一个函数
- PHP code
<!-- Code highlighting produced by Actipro CodeHighlighter (freeware) http://www.CodeHighlighter.com/ -->function listlist(&$num) { //if(1==$page) $num_last=1; //else $num_last=$num-100+1; $file_name="data"; $real_num=0; for(;$real_num'; echo'<tr>'; echo'<td width="80%" style="font-size:13px;font-family=fantasy">'; //$message=fgets($fd_temp); echo $message[0]; echo"\n"; echo $i; echo'</td>'; echo'<td width="20%" style="font-size:13px;font-family=fantasy; text-align=center">'; echo"<a href="pre_delete.php?file=%24file_temp&num=%24i&max=%24max">删除留言</a>"; echo"</td>"; echo"</tr>"; //echo"<br>"; echo'<tr>'; echo'<td style="font-size:17px">'; for($i=1;$i"; echo"</td> </tr>"; echo''; } } $num--; }
这个函数是把php和html混杂在一起 ,对吗 行吗?
求高手赐教
------解决方案--------------------
个人觉得不能理解为“php和html混杂在一起”,php是服务器端的语言,服务器执行完之后,将结果吐回到到客户端显示~ 上面的代码只是拼接出一段html,直接在浏览器显示。吐回来的仅仅是一个结果,至于怎么用,完全取决于前端想怎么处理
------解决方案--------------------
所谓混杂是说代码混杂在一起,一般是不建议这么做的,楼主可以去参考一些模板的写法
代码乱以后不好维护.看一次蛋痛一次,这可不是痛一痛就习惯了
------解决方案--------------------
理论上是可以的,运行的结果就是一个table呀,但是最好不要这样,html和php分开
------解决方案--------------------
php处理的最终结果是要么输入到数据库或磁盘文件,要么输出到浏览器。
------解决方案--------------------
php和html代码混合在一起,这是常态,没什么不对的
虽然看上去不太舒服,修改起来一比较麻烦。但这是必须的,因为你需要在HTML中嵌入动态内容,而这些动态内容有需要用HTML标记包裹
当然你可以使用模板引擎将PHP代码和HTML代码分开,但最终执行的还是混合的代码。只是混合由模板引擎完成,而不是由你完成

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
