PHP新手疑惑
以前学过.net与java 

目前自己看了看PHP 发现PHP较之前两个 好像封装的很不好,感觉好像ASP

看了看PHP说明 上面说PHP也有面向对象的设计模式 MVC 等等框架。

下面是这几天看PHP 中一些不懂得问题 希望高手解答疑惑!感激不尽

1.PHP中有无类似List 中泛型 数组的东西?

我定义了一个Model(UserInfo) 
当我查询数据库所有的Userinfo结果集的时候 我该怎么获得 然后再也没显示呢?

2.PHP 中如何实现 WEB与PHP代码的分离?
例如java中的servlet与jsp页面那样?

------解决方案--------------------
1,
$m = M('UserInfo');
$list = $m->select();
/*
$this->assign(...$list);
$this->display;
*/
print_r($list);

2,模板替换,就是1中的assign,其实就是将$list变量替换到预先写好的模板文件中的对应位置, 这个模板一般和当前控制器同名, 在Tpl目录下。


MVC... 你非要像JAVA那样的MVC, 在PHP里真心没必要, 在PHP里个人感觉MVC更多的是编程设计的概念, 框架非常多, 都是爱好者写的, 不就是分层么, 谁都会, 只是何必去照某个框架规矩办事呢, PHP就应该足够简单,足够敏捷,框架是个人习惯,想用也很简单,可以说太简单。

------解决方案--------------------
1: 有数组
2: 实例化后调用类方法即可。
3:smarty/自定义模板

PHP code

1

#1:$result = mysql_query("SELECT id, name, salary FROM employees",$conn);while (list($id, $name, $salary) = mysql_fetch_row($result)) {    echo " <tr>\n".         "  <td><a href="%5C%22info.php?id=%24id%5C%22">$name</a></td>\n".         "  <td>$salary</td>\n".         " </tr>\n";}#不过一般将其循环的结果集放入数组,然后再页面调用,便于读懂代码,这就涉及到第二个问题:#php code:$result = mysql_query("SELECT id, name, salary FROM employees",$conn);$arr = array();while ($rows = mysql_fetch_array($result,MYSQL_ASSOC)) {     array_push($arr,$rows);}#html code:<?php if(!empty($arr)){    foreach($arr as $array){?>

Copy after login
ID =$array['id']?>
Name =$array['name']?>

------解决方案--------------------
上面的同学们都已经从不同角度回答了一些,
我再说两句,

0. php的确不如.net/java封装得好. 因为php是一个渐变的语言, 从过程逐渐发展到OO, 它同时也是一个合作开发的开源语言, 不同的作者会带给它不同风格的东西,同时因为流行的程度,兼容也很重要. 无法像.net那样彻底抛开asp. 

1. php有array,可以当list使用,spl里也提供了其它一些容器. 
但是php里不会有泛型的概念,因为php是动态类型

2. 模板. 参加楼上们的回答

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

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,
