韩顺平 PHP视频教程 zend framework第1讲 zend介绍 zend快速入门
Mvc 框架 –zend framework
一 zend framework的简介
1 php流行的MVC框架介绍
a zend framework
b thinkphp(国人开发)
c yii(外企用的比较多)
d cakephp
m model模型
v view 视图
c controller控制器
核心的设计思想:把数据的输入,数据的处理,数据的显示分开。
框架:有zend framework提供一个目录结构和规范,我们程序员只需要在规定的文件和位置写自己的代码就ok了。
优点:
a 程序更加规范
b 程序的开发效率提高了
c 程序的可读性增加
d 程序的可维护性增加了
不足:
配置比较复杂。
二 为什么有zend framework
三 zend framework的原理
四 zend framework版用户登录系统
五 zend framework的投票系统
六 zend framework购物车系统

快速体验案例
目的是让大家开发zend framework项目的基本流程,配置如何处理。
配置成功后,可以看到欢迎界面即可。
开发步骤:
1 下载一个最新的zend framework
2 创建一zend framework工程
2.1 手工创建
2.2 Zf.bat创建
2.2.1 进入zf.bat所在目录
2.2.2 使用命令zf.bat create project 项目的全路径
2.2.3 zendstudio 创建
2.2.4 拷贝直接创建
2.2.5 引入库到项目中 library目录下库大库小不影响,因为php主要是编译
2.2.6 开始配置apache,让它支持apache框架
2.2.7 开启PDO和PDO相关的数据库引擎
Php.ini中开启extension=php_pdo_mysql.dll
如果是php5.2 应该直接启动extension=php_pdo.dll
Apache的配置文件httpd.conf配置文件,修改如下
LoadModule rewrite_module modules/mod_rewrite.so
修改AllowOverride None为
AllowOverride All

配置虚拟主机:
如果开发环境是自定义安装:
启动虚拟主机,httpd.conf配置文件,修改如下
# Virtual hosts
Include "conf/extra/httpd-vhosts.conf"
Httpd-vhost.conf文件配置 配置我们自己的虚拟主机
#配置我们自己的虚拟主机
DocumentRoot "F:/xampp/htdocs/zendfrm/public"
ServerName harry.com
DirectoryIndex index.php http://harry.com/index.php
# This should be omitted in the production environment
SetEnv APPLICATION_ENV development
Options Indexes MultiViews FollowSymLinks
AllowOverride All
Order allow,deny
Allow from all
再hosts中添加dns目录
harry.com

总控index.php每次都经过这。即使输入harry.com/uu,只要保证前面的域名不变化,怎么访问资源都会到总控。
重写机制 .htaccess
RewriteEngine On 启用重写机制
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ index.php [NC,L]
. 除了\n的任意字符。
在php项目中,我们通过对url的重写,可以完成整个只有一个入口的项目
.htaccess
多入口
RewriteRule ^.*$\.php enter.php
RewriteRule ^.*$\.html enter.html
Index发送给apache rewrite机制记录下来 首先调用总控——boot——
约定俗成
如果有错误 ErrorController.php 该控制器来处理,它是处理机制。我们的控制器 区分大小写。
xxAction 的格式 xx不能大写
总控使用了一点反射机制。
步骤
1 先在controllers文件下添加
class testController extends Zend_Controller_Action{
public function init(){
}
public functionloginAction(){
//echo '用户登录';
$this->render("login");
}
}
优化代码:
Bootstrap.php 数据库初始化代码的优化。
抽象出来一个类
//做一个父类,专门供其它的Controller来继承
class BaseController extends Zend_Controller_Action{
public function init()
{
//初始化我们的数据库适配器
$url=constant("APPLICATION_PATH").DIRECTORY_SEPARATOR.'configs'.DIRECTORY_SEPARATOR.'application.ini';
$dbconfig=new Zend_Config_Ini($url,"mysql");
$db=Zend_Db::factory($dbconfig->db);
$db->query('SET NAMES UTF8');
Zend_Db_Table::setDefaultAdapter($db);
}
}

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,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.
