网络编程 php C/C++
接触和学习(培训)php一年了,工作也快半年了,现在想转学C/C++,主要是服务器端和网络编程这一块,之前也没学过,熟悉一点Linux,转的原因也只是因为兴趣,现在阶段可以转吗?回复讨论(解决方案)
想学就学,不存在“转”
当然可以,就是一门语言而已,你需要学习的是编程的思想和设计的理念。
想学就学,不存在“转” 嗯。
当然可以,就是一门语言而已,你需要学习的是编程的思想和设计的理念。
现在只是感觉有些模糊的思想,设计也还远着呢?有时候也会去想怎么去设计自己的代码,怎么去设计一个类,但是工作内容大部分是复制粘贴,,,忧桑,
既然开始了php,为什么又要转c呢!你不怕到最后什么都没搞定,什么都不精么!真的有兴趣你当初培训的时候就不会选择php,所以我断定你学C走不了多远
先精通,再涉猎所有吧。

因为大学打了三年魔兽,毕业迷茫了,,学php之前还不知道php干什么的,只是跟着同学培训了,当时就想找个稳定工作,培训到工作疯狂的学了一年,了解了不少互联网的东西,大学那会对C也是有些兴趣的,只是兴趣没能抵挡住诱惑,所以现在才会有这个想法,也是想走的更远。

都说要先深后广,但是精通一门语言需要的时间都太长了,所以想选择一个自己喜欢的,,
学java的话,会对php有极大加强作用。c/c++这玩意,不是几年能精通的。

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.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.

Key players in HTTP cache headers include Cache-Control, ETag, and Last-Modified. 1.Cache-Control is used to control caching policies. Example: Cache-Control:max-age=3600,public. 2. ETag verifies resource changes through unique identifiers, example: ETag: "686897696a7c876b7e". 3.Last-Modified indicates the resource's last modification time, example: Last-Modified:Wed,21Oct201507:28:00GMT.

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.
