php Laravel 框架之建立后台文件夹
今天研究了在Laravel框架中的控制器中添加后台的文件夹.发现了一些小的规律,拿来和大家分享一下吧.
通常情况下,我们是直接在controllers文件夹中添加我们的控制器,然后再routes.php 路由表中寻找相应的控制器和action进行处理.但是现在有个问题,如果我们的前台和后台同在一个项目中,也就是说前台和后台的控制器会在一块.当然不是没有办法进行区分.我们可以在控制器前面加上Front,Admin等标记来分别前台控制器和后台控制.
这里我给大家提供一种方法来将前后台的控制器进行分离.
首先我们在controllers文件夹中建立一个admin文件夹.
第一种方法:直接在后台建立控制器,比如AdminController.php 里面正常的写上我们的内容.
在路由表中,
Route::get('admin',[email protected]');
我们发现程序报错,说无法找到控制器AdminController.
我们打开命令行工具,进入到该项目的更目录中,也就是artisan,composer.json所在的目录中,
运行命令 composer dumpautoload 或者 composer dump-autoload
这是对自动加载进行优化.
我们运行完命令之后,进入vendor目录的composer目录中,
我们查看一下我们的autoload_classmap.php文件,发现里面多了个AdminController的一条记录.
对了,然后我们刷新一下浏览器,就能够看到该后台控制器的内容了.
但是这个有个缺点,就是每次添加新的控制器的时候都必须要运行一下这个命令才行..
还有一点需要注意的是:如果你的后台文件夹中出现了和前台相同的控制器的时候,这是的程序会报错.
提示后台和前台有个控制器名字相冲突.
这里的解决方案是在后台使用名字空间进行处理.
比如我们我的后台同样有个IndexController控制器
namespace Controllers\Admin;
class IndexController extends \BaseController{
public function index(){
}
}
?>
这里还是要注意一点了,当使用名字空间之后,我们在里面使用的所有静态类都默认是当前名字空间的类.所以有时我们需要使用use View; Use ...等之类的名字空间.
同时在路由表中我们同样要使用 Controllers\Admin\[email protected] 这样的控制器来处理请求.
好了,这就是我学到的内容,拿来和大家分享分享.

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.
