Is php considered a well-designed language?

Is PHP really the best language in the world?

If you look closely, you will find that this is actually a joke. Not only is it difficult to say that PHP is the best language, it has even been despised as a programming language all year round. downstream of the chain. (Recommended learning: PHP programming from entry to proficiency)

It is true that PHP has its own historical baggage and many unreasonable aspects in its design, but it is for rapid development Designed for WEB applications, it is convenient, flexible and powerful, which has greatly promoted the prosperity and development of WEB applications. For a long time, it has been the best choice to quickly build WEB sites.

But precisely because it is too convenient and flexible, and the learning threshold is low, many programmers with weak foundations can quickly complete development requirements, but they also leave a lot of code with poor readability and difficulty in maintaining. .

As a PHP programmer, how do you write high-quality code in this imperfect language?

1. There must be good development specifications

The code is highly readable: There must be a mature naming convention. Good code should be self-describing. , appropriate comments should be made where objects, methods, and functions are difficult to understand;

Low code redundancy: high reusability of programs and files, high cohesion, and low coupling;

High execution efficiency: Try to use the simplest program flow to realize application requirements, and do not make big detours;

Defensive programming thinking: Be a vigilant programmer, and do it wherever there is user input and uploaded files. Do a good job of checking, maybe a momentary negligence of the programmer will cause a system to crash instantly.

2. Try to understand the underlying mechanism of PHP

It is easy to get started with PHP, but it is not easy to master it.

PHP is a dynamic language. If you want to make good use of it, you must first understand its underlying working principles. The memory management and framework model are worthy of our reference. We should know ourselves and our enemies, and use our strengths and avoid weaknesses. When necessary, we can implement more powerful functions through extended development and optimize the performance of our programs.

3. Need to follow up on the development of PHP

Since Rasmus Lerdorf created PHP in 1994, the PHP development team has been committed to solving the PHP community's needs to provide better performance, Requirements for scalability and less memory usage.

PHP7 has re-designed the Zend engine, which has greatly improved performance and also brought many practical new features.

As a developer, of course, you must keep up with the times as much as possible.

4. Try to use an efficient framework

For PHP, a framework is not necessary. A .php file can complete a page.

But a good framework can not only standardize the organization of the code and maintain a reasonable structure, but also enable the program to run efficiently.

The PHP ecosystem is very rich, with many excellent frameworks, such as Laravel, ThinkPHP, Yii, Yaf, etc. Among them, Yaf, which is implemented using PHP extensions, is famous for its high performance.
