With the widespread use of web applications, more and more developers are looking for an efficient and fast way to build their applications. In recent years, ThinkPHP6, as an excellent PHP framework, has gradually become the leader in the entire field.

In this article, we will introduce how to use ThinkPHP6 to create efficient web applications, allowing you to easily cope with various challenges in your business.

1. Introduction to ThinkPHP6

ThinkPHP6 is a lightweight, high-performance PHP framework that provides developers with a wealth of tools and functions to help develop to quickly build web applications. It has a complete MVC architecture, multiple template engines, caching mechanisms, ORM, Db, Session and many other tools, and all support dependency injection.

ThinkPHP6 not only supports object-oriented programming, but also functional programming, and can also support features such as chain calls. At the same time, it has very complete documentation and community support, which can quickly help developers learn and get started.

2. Install ThinkPHP6

Before starting development, we need to install ThinkPHP6 first.

First, we need to install ThinkPHP6 through Composer:

composer create-project topthink/think myapp 6.0.*-dev

After the installation is completed, we can start development in the myapp directory.

3. Create your first ThinkPHP6 application

ThinkPHP6 provides a command line tool that can help us quickly create applications. We only need to enter in the command line:

php think create:app myapp

where, myapp is the name of the application we want to create.

Next, we need to create a database.php file in the config directory and write the following content:

<?php
return [
    // 數(shù)據(jù)庫類型
    'type'            => 'mysql',
    // 數(shù)據(jù)庫連接DSN配置
    'dsn'             => '',
    // 服務(wù)器地址
    'hostname'        => '127.0.0.1',
    // 數(shù)據(jù)庫名
    'database'        => 'test',
    // 數(shù)據(jù)庫用戶名
    'username'        => 'root',
    // 數(shù)據(jù)庫密碼
    'password'        => '',
    // 數(shù)據(jù)庫連接端口
    'hostport'        => '',
    // 數(shù)據(jù)庫連接參數(shù)
    'params'          => [],
    // 數(shù)據(jù)庫編碼默認(rèn)采用utf8
    'charset'         => 'utf8mb4',
    // 數(shù)據(jù)庫表前綴
    'prefix'          => '',
    // 數(shù)據(jù)庫調(diào)試模式
    'debug'           => true,
    // 數(shù)據(jù)庫部署方式:0 集中式(單一服務(wù)器),1 分布式(主從服務(wù)器)
    'deploy'          => 0,
    // 數(shù)據(jù)庫讀寫是否分離 主從式有效
    'rw_separate'     => false,
    // 讀寫分離后 主服務(wù)器數(shù)量
    'master_num'      => 1,
    // 指定從服務(wù)器序號
    'slave_no'        => '',
    // 是否嚴(yán)格檢查字段是否存在
    'fields_strict'   => true,
    // 數(shù)據(jù)集返回類型
    'resultset_type'  => 'array',
    // 自動寫入時(shí)間戳字段
    'auto_timestamp'  => false,
    // 開啟斷線重連
    'break_reconnect' => true,
    // 記錄SQL日志
    'sql_log'         => true,
];

After creating the config file, we can start writing our first Controller, we can create an Index.php file in the app/controller directory and write the following content:

<?php
namespace appcontroller;

class Index
{
    public function index()
    {
        return 'Welcome to ThinkPHP6!';
    }
}

Next, we need to define the mapping of the controller in the routing. We can add the following content to the app/route.php file:

<?php
use thinkacadeRoute;
Route::get('/', 'Index/index');

Finally, we can start the application from the command line:

php think run

Visit http://localhost in the browser: 8000/ to see the "Welcome to ThinkPHP6!" message.

4. Use ThinkPHP6 for multi-language support

Multi-language support is an essential feature in a Web application. ThinkPHP6 provides us with a very convenient way to support multiple languages, allowing us to easily handle multi-language issues.

First, we need to create a lang.php file in the config directory, which defines the language types supported by our application and the corresponding language pack files:

<?php
return [
    // 默認(rèn)語言
    'default_lang'    => 'zh-cn',
    // 支持的語言列表
    'support_langs'   => [
        'zh-cn',
        'en-us',
    ],
    // 語言包目錄
    'lang_pack_path'  => app_path() . 'lang',
];

After defining After adding our language support, we also need to create the corresponding language pack file. We can create two folders in the app/lang directory: zh-cn and en-us to place Chinese and English language pack files respectively.

In the language pack file, we can define various error prompts, prompt information, etc. For example, create the messages.php file in the zh-cn directory and write the following content:

<?php
return [
    'welcome' => '歡迎來到ThinkPHP6!',
];

Then, in our controller, we can call the Lang::get() function to get what we need Multilingual information. For example, we can write our controller like this:

<?php
namespace appcontroller;

use thinkacadeLang;

class Index
{
    public function index()
    {
        return Lang::get('welcome');
    }
}

When we access the application in the browser, the current language type will be automatically determined based on the Accept-Language parameter in the request header, and the corresponding Multilingual information.

5. Use ThinkPHP6 for caching operations

Caching technology is an essential feature in a Web application, which can make our application respond more quickly. ThinkPHP6 can provide us with a comprehensive caching mechanism, allowing us to deal with caching issues more conveniently.

First, we need to create a cache.php file in the config directory, which defines the cache configuration that we need to use in our application:

<?php
return [
    // 默認(rèn)緩存驅(qū)動
    'default' => 'file',
    'stores'  => [
        // 文件緩存
        'file'  => [
            // 驅(qū)動方式
            'type'       => 'File',
            // 緩存保存目錄
            'path'       => app()->getRuntimePath() . 'cache',
            // 緩存前綴
            'prefix'     => '',
            // 緩存有效期（0表示永久有效）
            'expire'     => 0,
            // 緩存標(biāo)簽前綴
            'tag_prefix' => 'tag:',
        ],
        // Redis緩存
        'redis' => [
            // 驅(qū)動方式
            'type'       => 'redis',
            // 服務(wù)器地址
            'host'       => '127.0.0.1',
            // 服務(wù)器端口
            'port'       => 6379,
            // 密碼
            'password'   => '',
            // 數(shù)據(jù)庫
            'select'     => 0,
            // 緩存有效期
            'expire'     => 0,
            // 緩存前綴
            'prefix'     => '',
            // 緩存標(biāo)簽前綴
            'tag_prefix' => 'tag:',
        ],
    ],
];

After defining the cache configuration , we can use the Cache class to perform caching operations.

For example, we can cache a piece of information for 10 seconds:

<?php
use thinkacadeCache;

// 寫入緩存
Cache::set('hello', 'world', 10);

// 讀取緩存
echo Cache::get('hello');

We can also perform tag operations on the cache, for example:

<?php
use thinkacadeCache;

// 寫入緩存，并打上標(biāo)簽
Cache::tag('mytag')->set('hello', 'world');

// 根據(jù)標(biāo)簽清除緩存
Cache::tag('mytag')->clear();

6. Use ThinkPHP6 ORM operation

ORM technology is one of the most powerful technologies in web application development. It can help us simplify database operations and improve work efficiency.

ThinkPHP6 also provides us with the ORM function of Out Of The Box, allowing us to use PHP for database operations.

First, we need to create a database.php file in the config directory, which defines the database configuration that we need to use in our application:

<?php
return [
    // 數(shù)據(jù)庫類型
    'type'            => 'mysql',
    // 數(shù)據(jù)庫連接DSN配置
    'dsn'             => '',
    // 服務(wù)器地址
    'hostname'        => '127.0.0.1',
    // 數(shù)據(jù)庫名
    'database'        => 'test',
    // 數(shù)據(jù)庫用戶名
    'username'        => 'root',
    // 數(shù)據(jù)庫密碼
    'password'        => '',
    // 數(shù)據(jù)庫連接端口
    'hostport'        => '',
    // 數(shù)據(jù)庫連接參數(shù)
    'params'          => [],
    // 數(shù)據(jù)庫編碼默認(rèn)采用utf8
    'charset'         => 'utf8mb4',
    // 數(shù)據(jù)庫表前綴
    'prefix'          => '',
    // 數(shù)據(jù)庫調(diào)試模式
    'debug'           => true,
    // 數(shù)據(jù)庫部署方式:0 集中式(單一服務(wù)器),1 分布式(主從服務(wù)器)
    'deploy'          => 0,
    // 數(shù)據(jù)庫讀寫是否分離 主從式有效
    'rw_separate'     => false,
    // 讀寫分離后 主服務(wù)器數(shù)量
    'master_num'      => 1,
    // 指定從服務(wù)器序號
    'slave_no'        => '',
    // 是否嚴(yán)格檢查字段是否存在
    'fields_strict'   => true,
    // 數(shù)據(jù)集返回類型
    'resultset_type'  => 'array',
    // 自動寫入時(shí)間戳字段
    'auto_timestamp'  => false,
    // 開啟斷線重連
    'break_reconnect' => true,
    // 記錄SQL日志
    'sql_log'         => true,
];

After defining the database configuration , we can use model classes to perform ORM operations. For example, we can create a User model class to correspond to the users in our database table:

<?php
namespace appmodel;

use thinkModel;

class User extends Model
{

}

Then, we can use the model class to perform various operations on the database. For example, we can add a new user record:

<?php
use appmodelUser;

// 新增一條用戶記錄
$user = new User;
$user->username = 'test';
$user->password = 'test';
$user->save();

We can also query a user record:

<?php
use appmodelUser;

// 查詢一條用戶記錄
$user = User::where('username', 'test')->find();

Of course, in addition to basic addition, deletion, modification and query, we can also perform more complex Database operations, such as transaction processing, etc.
