setCookie设置的cookie,会已hhtp响应头的形式,写入浏览器,若path,domain等匹配,将会在下一次HTTP发送请求时加入HTTP请求头。二者只是设置的方式不一样,但一旦设置成功,都可以在浏览器开发者工具中看到。
可以参考下我以前回答的一个问题 http://segmentfault.com/q/1010000002655809/a-1020000002655842
PHP setcookie函数,是通知浏览器,把这个cookie保存起来;浏览器HTTP请求发送的COOKIE是把之前保存的cookie发送给服务器,告诉服务器,我是有这个cookie的。
其实你首先要理解从cookie的作用,他就是服务端生成之后发给客户端,用于验证用户的身份用的。这样客户端(浏览器)向服务器发送请求时就将cookie也发送到服务器,这样服务端只要查一下你的cookie是不是对的,这样就不用每次都去查一下用户的账号密码是不是正确的。(当然cookie还是有其他作用的,例如储存用户的访问习惯之类的)。
而对于你的问题
客户端(浏览器):HTTP请求发送的cookie就是服务器生成后发给浏览器,浏览每次向服务器发送请求都携带回去的。
服务端:PHP的setcookie,其实就是服务端生成cookie的过程。
两者就是同一个东西。所以在浏览器看到的就是同一个东西。
1 Cookie是统一的标准,用什么方式发送,都应该是一样的,否则就失去了它存在的意义。
2 浏览器是不会发送Cookie的,所以也就不存在“浏览器HTTP请求发送的COOKIE”,都是从server端发送给浏览器的,因为http是个无状态协议,只有使用cookie和session,来分辨某个用户的身份。

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
