Download the completed directory:

Tp5├─application                   application directory ├─extend                                        extension Class Library directory (definable) ├─public                                        Web site access directory ├─runtime                                   runtime Catalog (definable) ├─vendor                                        Third-party Class library catalog (Composer) ├─thinkphp                              Framework Core Catalog ├─build.php                         Auto-Generate definition file (reference) ├─composer.json         Composer definition file ├─license.txt                   Authorization Notes file ├─readme.md                         README  file ├─think                                         command line tool entry

The structure of the core framework directory is as follows:

├─thinkphp Framework System catalog │├─lang Language Pack directory │├─library Framework Core Class Library Catalog ││├─think think class Library                                                               Package directory ││└─traits System traits directory │├─tpl  System template directory │││├─.htaccess for Apache                                          The rewrite │├─.travis.yml CI definition file │├─base.php                               Framework base File │├─composer.json composer definition file │├─console.php Console Portal File │├─convention.php custom configuration file │├─helper.php Helper function file (optional) │├─license.txt Authorization note File │├─phpunit.xml Unit test configuration  File │├─readme.md                                   README file │└─start.php Framework boot file 

2. Running

I am using Kali's own apache2 server, using service apache2 start boot, need to put git down the entire project into the server running directory, linux default is:

/var/www/html

Then enter it on the browser side: http://localhost/tp5/public/
You can see the Welcome page:

If you don't want to install any WEB server, you can also use PHP's own WebServer and run router.php to run your tests.
Go to the command line and enter the Tp5/public directory, entering the following command:

Php-s  localhost:8888  router.php

Next you have direct access to

http://localhost:8888

3. Directory structure

The most common concern is the application directory:

├─application app directory (can be set) │├─index       Module catalog (can change) ││├─config.php module configuration file │        │├─common.php Module Common file ││├─controller Controller directory ││                                              ├─model Model Catalog ││└─view                                    View Catalog │││├─command.php command-line tool configuration file │├─common.php                                          Apply a common file │├─config.php application profile │├─tags.php                                     Apply the behavior extension definition file │├─database.php database configuration file │└─route.php Routing configuration File 

Version 5.0 has a modular design architecture, the default application directory below is only one index module directory, if you want to add a new module can be generated using console commands. Switch to command-line mode, go to the app root (tp5 below) and execute the following command:

PHP think   build   --module    Demo

A default demo module is generated, including the following directory structure:

├─demo│       ├─controller                        Controller Catalog │       ├─model                                         model Catalog │       ├─view                                              View catalog │       ├─config.php                        Module Profile │                        The └─common.php module common file also generates a default Index controller file.

4. Template rendering

The first is the controller:
is located application/index/controller/Index.php with a default index class:
Originally it was return to the start page and now to Hello World.

<?phpnamespace   app\index\controller;class index{public        Function Index ()        {            return  ' hello,world! ';        }}

Then we inherit the controller class:

<?phpnamespace App\index\controller;use think\controller;//introduces Controller class index extends controller{    Public Function Index ($name = ' world ')    {        $this->assign (' name ', $name);        return $this->fetch ();}    }

We pass a parameter with a default value to the page name.

Then the view:
Thinkphph with template rendering, template exists under the View folder, default is no view folder, we create:
application/indexCreate a view directory below the directory, build an index directory under the View directory, and then add the template file hello.html, the entire path:view/index/hello.html

Then we can access:

Or take the omitted path: http://localhost/tp5/public/
More advanced routes that can configure URLs.

5. Accessing the database

The MySQL database is used here and a database is built under the test table:

CREATE table if not exists think_data (ID int (8) is not NULL Auto_increment primary key, data varchar (255) is not null) engine=m Yisam default Charset=utf8;
Insert a few more data on the line;
Then application/database.php configure the following:

return [    //Database type ' type    '           = ' mysql ',//    server address    ' hostname '       = ' 127.0.0.1 ',    //database name    ' database ' =       ' Test ',//    user name    ' username ' + '       root ',    //password    ' password '       = > ',    //Port    ' hostport ' + ',//    connect DSN    ' dsn ' = '            ,    //database connection Parameters    ' Params ' =         = [],    //Database encoding defaults    to UTF8 ' charset ' = ' utf8 '        ,    //database table prefix    ' prefix '         = > ' think_ ',    ///Database Debug mode    ' Debug '          =-true,
Modify the Index class under controller:

<?phpnamespace app\index\controller;use think\controller;use think\db;//Introduction Database class Index extends controller{    Public Function Index ($name = ' world ')    {        $this->assign (' name ', $name);        return $this->fetch ();    }    Public Function dbtest ()    {        $data = db::name (' data ')->find ();        $this->assign (' result ', $data);        return $this->fetch ();}    }
Then create a dbtest.html render in the index directory under view:


can be accessed again http://localhost/tp5/public/index.php/index/index/dbtest .
