Tp Application 目录的Common 文件夹中 新建了类以供Controller 使用。
Common 文件中的 A 类 去掉用 vendor 中的第三方库
Tp 版本 3.2.3
问题如下
一、通过调用composer 的 autoload.php 文件去加载第三方库资源,无法正确引用到 ,提示我要用的类不存在
( 主要是想调用ffmpeg这个工具来裁剪视频)
尝试过 直接通过require去引用 因为涉及到的引用很多觉得这是不靠谱的,
通过vendor函数去引用也未能解决问题。
现在是 通过
require __DIR__.'/../../../ThinkPHP/Library/vendor/autoload.php';
加上 use 去引用
二、 use 和require 的关系是什么?
分不多了,求帮助
回复讨论(解决方案)
以上图片分别为
引用
第三方类库
调用
程序结构
错误提示
针对 composer 自动加载有什么经验也麻烦讲解一下,php新手 多指教
记得第三方类库应放在 ORG 目录中,用 ORG 函数引用
记得第三方类库应放在 ORG 目录中,用 ORG 函数引用
除了位置这个,上面提供的信息能看出程序的错误点吗?
谢谢各位,我已经通过其他的方式解决了。
个人感觉 tp导入第三方框架比较坑。使用起来蛋疼。

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

The reasons why PHP is the preferred technology stack for many websites include its ease of use, strong community support, and widespread use. 1) Easy to learn and use, suitable for beginners. 2) Have a huge developer community and rich resources. 3) Widely used in WordPress, Drupal and other platforms. 4) Integrate tightly with web servers to simplify development deployment.

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.
