route(路由)–>controller(控制器)–>view(视图)工作流程
基本的工作流程如如图
-
一般的laravel路由写法,直接将匿名函数写进去路由里面
Route::get('/',function(){return view('welcome'); //welcome是laravel的blade模板引擎的文件名字})
传统的是根据文件目录位置来写php
/blog/index.php /blog/about.php访问的时候是 http://localhost/blog/index.php,现在通过route来统一控制
-
由于laravel的route支持controller,所以可以这样写,传入一个controller然后用@来调用controller里面的方法,所以可以将匿名函数的写法改为这样
Route::get('/','SiteController@index');对比一下:
Route::get('/',function(){return view('welcome'); //这是匿名函数的路由})Route::get('/','SiteController@index'); //这是使用controller的路由
通过命令行可以创建controller
php artisan make:controller SiteControllerController created successfully.
在刚创建的controller里面写一个刚才调用的方法index()
class SiteController extends Controller //所有的controller都是继承自Controller这个类{ // public function index(){ return view('welcome'); //这个index方法里面就直接返回一个view视图,这个视图的文件是welcome.blade.php }}
-
关于view视图的blade引擎模板
- blade引擎模板一般存放在app/resource/views目录下面的,模板以.blade.php结尾
- view命令默认读取app/resource/views作为根目录,所以可以直接view(‘welcome’),意思是view一个在app/resource/views这个目录下的一个名叫welcome.blade.php的文件,view可以直接识别blade.php,所以可以省略。
- blade模板文件其实也是一个html文件,只是可以写一些laravel支持的模板语法,来实现数据交互

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.

In PHP, trait is suitable for situations where method reuse is required but not suitable for inheritance. 1) Trait allows multiplexing methods in classes to avoid multiple inheritance complexity. 2) When using trait, you need to pay attention to method conflicts, which can be resolved through the alternative and as keywords. 3) Overuse of trait should be avoided and its single responsibility should be maintained to optimize performance and improve code maintainability.

Dependency Injection Container (DIC) is a tool that manages and provides object dependencies for use in PHP projects. The main benefits of DIC include: 1. Decoupling, making components independent, and the code is easy to maintain and test; 2. Flexibility, easy to replace or modify dependencies; 3. Testability, convenient for injecting mock objects for unit testing.

SplFixedArray is a fixed-size array in PHP, suitable for scenarios where high performance and low memory usage are required. 1) It needs to specify the size when creating to avoid the overhead caused by dynamic adjustment. 2) Based on C language array, directly operates memory and fast access speed. 3) Suitable for large-scale data processing and memory-sensitive environments, but it needs to be used with caution because its size is fixed.

PHP handles file uploads through the $\_FILES variable. The methods to ensure security include: 1. Check upload errors, 2. Verify file type and size, 3. Prevent file overwriting, 4. Move files to a permanent storage location.

In JavaScript, you can use NullCoalescingOperator(??) and NullCoalescingAssignmentOperator(??=). 1.??Returns the first non-null or non-undefined operand. 2.??= Assign the variable to the value of the right operand, but only if the variable is null or undefined. These operators simplify code logic, improve readability and performance.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
