Yii (yiiframework) framework (2): Build the first Yii application

The yii framework has been installed before, now let’s create the first Yii application

1. Enter the directory of your website

2. Execute the command: YiiRoot/framework/yiic webapp testdrive

Note: The YiiRoot here is the installation directory of your Yii framework.

3. After entering the above command, a prompt message will appear:

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/php_pdo_mysql.dll' - 
/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/php_pdo_mysql.dll: cannot open shared object file: No such file or directory in Unknown on line 0
Create a Web application under '/home/wwwroot/test.yii.com/'? (yes|no) [no]:

Here it prompts whether to install the web application in this directory. We can directly enter yes to complete. Application creation.

4. Visit your application: http://hostname/index.php. We can see an application that includes a homepage, about page, contact page, and login page.
