This article introduces to you the things that you most want to know about hackers. With these things, many hackers can use them conveniently. The article explains to you whether hackers should learn PHP or Python, both. It is a common and relatively powerful language. This article is not a random analysis by the editor, but a serious thought. All the reasons are written in it. In addition to introducing whether hackers should learn PHP or Python at the beginning, I will also tell you later I have learned the ten differences between PHP and python, that is, the ten advantages and disadvantages. If you want to know, just read on.
First of all, let’s talk about what a hacker is:
To put it bluntly, a hacker is a programmer, but he is just a more powerful programmer. When it comes to hackers, what is in his mind? They are all about how to invade other people's computers and find the information you want to find.
Simple analysis, if a hacker wants to invade a website, he must distinguish whether it is a PHP-structured website or a Python-structured website. If you want to invade a PHP-structured website, you must first learn PHP, otherwise the invasion The difficulty will be great. The same is true if you want to hack into a website made of python, you need to be proficient in python. So there are a lot of things that hackers can learn. We shouldn’t take hackers for granted. Most hackers spend all day typing code in technology companies, earning the same salary as normal workers.
But what I want to say next is, what should be the common language used by hackers? Is it PHP? No, it’s python. Why? Because only those who have used python can understand it.
The power of python is that there are many third-party libraries, so that you can develop on the shoulders of giants and avoid repeated development wheels. python There are many ready-made libraries for what you want, you just need to use python to import them.
Like some websites with verification codes, you need to use the verification code recognition function that comes with the Python graphics library. You only need to use it, write down the logic responsible for cracking, and then you don’t have to worry about it. Python comes with a library for identifying verification codes. (Of course, I'm not a hacker, but using python is a lot more convenient in some aspects)
Okay, now that we've talked about python that hackers like to use, now let's take the entire The advantages of PHP and python Analyze the shortcomings.
I saw someone doing a good analysis on the Internet, and I think it’s right. Now I’m sharing it with you, so that you don’t have to look for it everywhere. (No need to thank me)
Analysis of ten advantages and disadvantages of PHP and Python:
1. Let’s talk about the learning cost that everyone is concerned about: PHP and learning cost are not It is very high. Its advantage is that it has relatively complete official Chinese documents, and the PHP application field is only in the Web aspect, so there is less content for us to learn. Because Python has many learning routes, it is not easy to find tutorials and materials that suit you, so this is a bit difficult.
2. The second point is about the application field: PHP is only used in the Web backend, and Python has a wider application field. If the logic needs to be transplanted to other platforms (such as desktop), Python is more user-friendly. .
3. The third point is about the community: PHP materials are everywhere, but they are all basic knowledge. The high-quality Chinese community is very good, but generally they are not very interested in the official new functions. focus on. Python is much better in this regard. At least those who want to learn can find good information if they search carefully.
4. It’s time to talk about grammar: PHP’s grammar looks like it has not been carefully designed and is very casual. Some syntaxes seem very convenient (using dots to connect strings), but they cause a lot of trouble for subsequent expansion (because dots cannot be used to access members of objects), and another example is the rather painful namespace syntax. Python is better in comparison, but there are some incompatible syntax changes between Python2 and Python3. (So you can judge for yourself who is better)
5. After talking about grammar, now let’s talk about writing HTML templates: PHP can be used directly to write HTML templates very conveniently, while Python needs to use other languages. or library to implement. (It’s obvious, so I won’t say it again)
6. Now let’s talk about the running mode: PHP running mode is relatively simple (php-fpm, mod_php), Python can be run with fastCGI, or you can run it by yourself Listen on the port to handle requests.
7. Let’s talk about the package manager: I’m afraid no one uses PHP’s package manager (PEAR) and extension manager (PECL) at all. This leads to the high cost of introducing a new dependency, so many people tend to Try to reinvent your own wheel rather than importing ready-made libraries. Python has a unified package manager. Although it has its problems, it is much better than PHP. The namespace management after introducing the library is also better than PHP.
8. The eighth point talks about extensions and libraries: Both PHP and Python can use C to write extensions. In comparison, Python has more libraries available. (So you can understand it)
9. It’s time to talk about performance: Because PHP has a single running method, the opcode caching solution is relatively mature (APC, opcache), and the opcode runs very quickly after caching. Python may need to do more to optimize performance on its own.
10. The last point is that we talk about the type system: PHP and Python are both dynamic types. PHP is relatively vague about type discrimination and has many traps, while Python is more strict.
The above ten points are all personal opinions. If you have different ideas, you can ask questions below or you can hold back.
