THINKPHP5 Get started this knowledge

One: module design

Single module By default, single module support, all modules with app as root namespace

Common module can be built, but not directly accessible, can be accessed in other modules, improve security

The common class can be arbitrarily inherited

II: Configuration of the TP5

1 Formula Configuration

Defining the configuration Directory

In the Portal file

Define (' Conf_path ', __dir__. /.. /conf/');

2 application Configuration

Create a new config in the previous section of the catalog. Php

return Array ();

Inside the array is the configuration item

3 Extended Configuration

Split the different configuration files into the configuration file can not be easily managed, in the Config directory to create a new extension configuration folder extra

Then create a new configuration file directly

such as qiniu.php

Configuration format is the same as on

TP5 allows database configuration to be placed directly under the Config folder (same level as config.php)

4 Scene Configuration

Different configurations used in the same scenario

Configure the App_status in config.php, and then set up the configuration of the environment in extra

5 module Configuration

Create a folder with the same module name under the Config folder, and then create a new config.php file

Module configuration of the directory and Config directory consistent, can create a new extra extension configuration, extension configuration only in the corresponding module has a role

6 Dynamic configuration

A. Configuration items in the __construct constructor in the controller that use the Assistant function Config can take effect in the controller

B. Using the helper function in a method new configuration item only takes effect in the modification method

7 Use of the Config class

To dynamically change the config configuration, you can use the Assistant function config () and use the Config class

Config (' key ', ' value ', ' scope ')

Determine if key exists

Config ('? key ');

8 Configuring and using environment variables

Three: Routing

1 entry file

Public/index.php Single Entry

2 Hidden Portal File

is both a hidden index.php

A open Apache's rewrite module, allowed all

B. htaccess configuration exists in the public directory and does not require its own configuration

2 Portal File Bindings

Bind module name, Shorten URI

For example, to bind a background module

Define Difine (' Bind_module ', ' admin ') in admin.php; Binding backend Modules

Difine (' Bind_module ', ' admin/index '); the Index controller that binds the background

Setting the ' Auto_bind_module ' =>true in the configuration file allows you to no longer define difine (' Bind_module ', ' admin ');

3 Routing

First turn on routing (default is on) Configure ' url_route_on ' =>true in the configuration file,

' Url_route_must ' =>false (true if routing must be configured to access)

Create a new routing file in the configuration file route.php

Direct Write routing rules

For example, return array (

' News/:id ' = ' index/index/news ',

);

Four: Request

1 Request Requests

A helper function request ()

Request class for B thinkphp

C Object injection, injecting the object into the method

2 Requesting Object request

A Get links in the browser

Get Domain name $request->domain ()

Get PathInfo $request->pathinfo ()

Get path $request->path ()

B Request Type

The type of the current request $request->method ();

Determine if a GET request $request->isget ()

Determine if an AJAX request $request->isajax ()

---Determine if the cell phone $request->ismobile ();

Parameters for C request
Get the parameter $request->get ()

Get all parameters (including path) $request->param ()

Get POST request $request->post ()

Get session $request->session ()

Get Cookie $request->cookie ()

D get module, CONTROLLER, operation

$request->module ();
$request->controller ();
$request->action ();
3 Input helper functions

Equivalent to the I function in tp3.2

Input (' Post.name ')

Input (' Get.name ')

Input (' Cookie.name)

Input (' Session.name)

...

You can get the various parameters in request

4 Response Object

Config (' default_return_type ', ' json '); return operation via dynamic modification of returned parameter types

More suitable for encapsulation of APIs

Type support json,xml,html (default)

For example:

Config (' default_return_type ', ' json ');
$res = [' Code ' =>200,
' Data ' =>[1,2,3,4,5,6,7,8,9]
];
return $res;

The JSON data is returned

Five views

Direct display

return view (); default is app/group name/view/Controller name/method name. html

Pass the first parameter

Return view (' name ') defaults to app/group name/view/controller name/name.html

Pass the first parameter

Return view (' name1/name2 ') defaults to app/group name/view/name1/name2.html

Return view ('./index.html ') defaults to the index,.html file in the index.php Portal file sibling directory

Passing values to the template

The second argument is in the form of an array

Return view (' name ', [' key ' = ' value '])
