Yii 记实录（1）

由于很多公司使用的Yii版本是1.1，所以先按照Version:1.1来进行说明，之后会补上2.0的版本，其实很多是PHP5.3新特性

Yii1.1文件结构如下

下载地址

下面的步骤已经确定你的linux中Apache/PHP等都搭建好，然后确定了Host或者虚拟目录了

我们将这些放到对应的目录

测试Demo Blog如下 

 

下面我们自己创建自己的Web应用

在根目录下创建index.php

<?php
$yii = dirname(__FILE__).'/framework/yii.php';
$config = dirname(__FILE__).'/application/config/main.php';

require_once($yii);
Yii::createWebApplication($config)->run();

创建application/config目录

创建配置文件main.php

<?php
return array(
    'basePath'=>dirname(__FILE__).DIRECTORY_SEPARATOR.'..',
    'name'=>'MyFirstWebApp',

    // preloading 'log' component
    'preload'=>array('log'),

    // autoloading model and component classes
    'import'=>array(
        'application.models.*',
        'application.components.*',
    ),

    'defaultController'=>'index',

    // application components
    'components'=>array(
        'user'=>array(
            // enable cookie-based authentication
            'allowAutoLogin'=>true,
        ),
        /*'db'=>array(
            'connectionString' => 'sqlite:protected/data/blog.db',
            'tablePrefix' => 'tbl_',
        ),*/
        // uncomment the following to use a MySQL database
        /*
        'db'=>array(
            'connectionString' => 'mysql:host=localhost;dbname=blog',
            'emulatePrepare' => true,
            'username' => 'root',
            'password' => '',
            'charset' => 'utf8',
            'tablePrefix' => 'tbl_',
        ),
        */
        'errorHandler'=>array(
            // use 'site/error' action to display errors
            // 'errorAction'=>'site/error',
        ),
        'urlManager'=>array(
            'urlFormat'=>'path',
            'rules'=>array(
                /*'post/<id:\d+>/<title:.*?>'=>'post/view',
                'posts/<tag:.*?>'=>'post/index',*/
                '<controller:\w+>/<action:\w+>'=>'<controller>/<action>',
            ),
        ),
        'log'=>array(
            'class'=>'CLogRouter',
            'routes'=>array(
                array(
                    'class'=>'CFileLogRoute',
                    'levels'=>'error, warning',
                ),
                // uncomment the following to show log messages on web pages
                /*
                array(
                    'class'=>'CWebLogRoute',
                ),
                */
            ),
        ),
    ),

    // application-level parameters that can be accessed
    // using Yii::app()->params['paramName']
    'params'=>require(dirname(__FILE__).'/params.php'),
);

在config中创建params.php

<?php

// this contains the application parameters that can be maintained via GUI
return array(
    // this is displayed in the header section
    'title'=>'MyFirstWebApp',
    // this is used in error pages
    'adminEmail'=>'webmaster@example.com',
    // number of posts displayed per page
    'postsPerPage'=>10,
    // maximum number of comments that can be displayed in recent comments portlet
    'recentCommentCount'=>10,
    // maximum number of tags that can be displayed in tag cloud portlet
    'tagCloudCount'=>20,
    // whether post comments need to be approved before published
    'commentNeedApproval'=>true,
    // the copyright information displayed in the footer section
    'copyrightInfo'=>'Copyright &copy; 2009 by My Company.',
);

下一步在与config同级创建controller、models、views

在controller中创建IndexController.php

<?php

class IndexController extends Controller
{
    // public $layout='column1';

    /**
     * Declares class-based actions.
     */
    public function actions()
    {
        return array(
        );
    }
    
    /**
     *  
     */
    public function actionIndex() {
        
    }    
    
    /**
     * This is the action to handle external exceptions.
     */
    public function actionError()
    {
        
    }

    /**
     * Displays the contact page
     */
    public function actionContact()
    {
        
    }

    /**
     * Displays the login page
     */
    public function actionLogin()
    {
        
    }

    /**
     * Logs out the current user and redirect to homepage.
     */
    public function actionLogout()
    {
        
    }
}

运行如果出现这样的错误，说明没有可写权限，付给目录可写入的权限

chmod -R ./runtime 777

OK，然后我们在Controller中添加内容，测试下

public function actionIndex() {
        echo "Hello World";
}    

看看是不是显示出来了。
