Thinkphp入门 二 (46),thinkphp入门46

【空操作处理】

看下列图:

  用户访问一个不存在的操作—》解决:给每个控制器都定义个_empty()方法来处理

  第二个解决方法:定义一个空操作

【空模块处理】

我们使用一个类,但是现在这个类还没有被include进来。

我们可以通过自动加载机制处理__autoload(),如果这个自动加载机制也没有找到这个类,就会报错。

即是请求一个空模块

  解决一:定义一个空的控制器、空模块

  解决方法二:

【给应用增加函数库文件】

在Common文件夹里面,便是放入我们函数库文件的地方

【模块分组】

  1. 控制器进行分组设置

  2. 视图模板需要分组

  3. 配置变量需要分组

  4. 做配置config.php

【前置操作、后置操作】

控制器里边的方法在被调用的时候,在调用之前、或调用之后可以做一些额外的工作,就称之为前置操作、后置操作

当我们请求这个网址:http://网址/index.php/Admin/Goods/zhanshi,在方法存在的情况下,这个动作在哪发生的,App.class.php  的exec()方法里边

  一个类里边有许多方法,都需要前置和后置操作,应该如何解决?

解决:

【跨模块调用】

实例化一个不存在的类,会通过__autoload()自动加载机制。

tp框架的__autoload()在哪?在Think.class.php

通过A()方法实例化控制器对象

  A(‘模块控制器’)   例如:A(‘Goods’)

  A(‘分组/控制器’)   例如:A(‘home/Ucenter’);

  A(‘项目://分组/控制器’)  例如:A(‘shop://home/Ucenter’);

    A()方法里边有嵌套调用import()方法,该方法帮助我们获得对应的控制器其,并require引入。A()方法顺便直接new 实例化对象

 

R(“项目://分组/控制器/操作”)方法

  是把控制器的引入、实例化对象、方法的调用都给继承好了。

  R(‘模块控制器/操作’)   例如:A(‘Goods’)

  R(‘分组/控制器/操作’)   例如:A(‘home/Ucenter/members’);

  R(‘项目://分组/控制器/操作’)  例如:A(‘shop://home/Ucenter/members’);

 

R()方法里边调用A()方法

A()方法里边调用import()方法

  A()方法使用

  R()方法使用

A Diffusion Model Tutorial Worth Your Time, from Purdue University A Diffusion Model Tutorial Worth Your Time, from Purdue University Apr 07, 2024 am 09:01 AM

Diffusion can not only imitate better, but also "create". The diffusion model (DiffusionModel) is an image generation model. Compared with the well-known algorithms such as GAN and VAE in the field of AI, the diffusion model takes a different approach. Its main idea is a process of first adding noise to the image and then gradually denoising it. How to denoise and restore the original image is the core part of the algorithm. The final algorithm is able to generate an image from a random noisy image. In recent years, the phenomenal growth of generative AI has enabled many exciting applications in text-to-image generation, video generation, and more. The basic principle behind these generative tools is the concept of diffusion, a special sampling mechanism that overcomes the limitations of previous methods.

Generate PPT with one click! Kimi: Let the 'PPT migrant workers' become popular first Generate PPT with one click! Kimi: Let the 'PPT migrant workers' become popular first Aug 01, 2024 pm 03:28 PM

Kimi: In just one sentence, in just ten seconds, a PPT will be ready. PPT is so annoying! To hold a meeting, you need to have a PPT; to write a weekly report, you need to have a PPT; to make an investment, you need to show a PPT; even when you accuse someone of cheating, you have to send a PPT. College is more like studying a PPT major. You watch PPT in class and do PPT after class. Perhaps, when Dennis Austin invented PPT 37 years ago, he did not expect that one day PPT would become so widespread. Talking about our hard experience of making PPT brings tears to our eyes. "It took three months to make a PPT of more than 20 pages, and I revised it dozens of times. I felt like vomiting when I saw the PPT." "At my peak, I did five PPTs a day, and even my breathing was PPT." If you have an impromptu meeting, you should do it

We know that LLM is trained on large-scale computer clusters using massive data. This site has introduced many methods and technologies used to assist and improve the LLM training process. Today, what we want to share is an article that goes deep into the underlying technology and introduces how to turn a bunch of "bare metals" without even an operating system into a computer cluster for training LLM. This article comes from Imbue, an AI startup that strives to achieve general intelligence by understanding how machines think. Of course, turning a bunch of "bare metal" without an operating system into a computer cluster for training LLM is not an easy process, full of exploration and trial and error, but Imbue finally successfully trained an LLM with 70 billion parameters. and in the process accumulate
