PHPThe ability to solve problems is undoubted
"I am a php programmer and often use Python in projects, but I admire PHP and its ability to solve problems Ability. PHP users keep growing because sometimes some poor soul wants to create an online encyclopedia, or a teacher needs an online teaching platform, or someone wants to write a blog. These people don't want to learn programming. Just trying to solve the problem.”
I want to say that this comment really hits the mark! I think this is the main reason for PHP's success.
People learn PHP because they have some problem they need to solve, and this is where PHP shines. You can simply open your static HTML page, add a simple
From there, you can write some simple scripts, learn how to process forms, talk to databases, etc. After a while you start using object-oriented programming and maybe some frameworks.
That’s basically how I got into programming.
PHP has a little different approach compared to many other languages. When learning other languages you need to study computer science for 5 years before you enter the real world where you need to solve problems. (You can certainly say that PHP is a language that has given birth to many programmers, while most other languages have made fewer and fewer programmers.)
You may ask about this: So, once you start learning Programming, why not switch to another language? To put it simply: PHP has some problems, but it's not that bad. Of course, people always try to tell you that, but it really isn't like that. The biggest criticism of PHP is that it really doesn't matter, like a needle of inconsistency and a haystack of chaos. At the top of things PHP made a few mistakes. But in reality it really makes no difference. Of course, it would be better if the order was consistent, but my IDE does a really good job of reminding me how to do things correctly.
To summarize:
PHP is a great language to get started with programming!
Once you start learning, PHP is also great for practical programming (you know, the ones that are useful for object-oriented)
PHP is not as bad as some people say. It's a little buggy, as every language is, but in practice PHP rarely has problems.
Also, I've noticed that most PHP detractors act like 10-year-olds when it comes to this language. For example, the following sentence from Jeff's article:
"What is frustrating is not the terrible design of PHP. Can anyone still deny that PHP is the worst-designed mainstream language that has destroyed our programming skills for decades? What is really frustrating What’s frustrating is that nothing has changed so far. “
This is too outrageous. PHP has changed a lot in recent years, but many people seem to only remember its image as an inferior language with poor OOP support in the PHP 4 era. Well, I'm going to break it for you: PHP 4 has been dead for almost ten years, and PHP 5 already has great support for object orientation, just like Java does. PHP 5.3 also adds support for namespace and lambda function combinations. And PHP 5.5 will add a lot of new and eye-catching features. And you're telling me nothing has changed?

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.
