Don't large websites use php?

In recent years, website construction has become more and more an indispensable part of people's lives and work. In website construction, website programming is an important link. As a server-side scripting language, PHP is widely used in the field of web development, but it is not commonly used in some large websites. So do large websites not use PHP? Next, we will explore this topic.

First of all, PHP is a weakly typed language. Compared with languages ​​such as C and Java, its syntax is simpler and the amount of code is smaller. Therefore, it is very suitable to use PHP in small-scale websites. , it has also been widely used. However, when the number of website visits is too large, PHP cannot fully meet the demand, because PHP's execution efficiency is low, and the high performance required by large websites has an extremely important impact on the access speed of the website.

At the same time, large websites have a huge number of databases, a huge amount of data, and high efficiency requirements for database operations. However, the database connected to PHP is inefficient when processing large-scale data. This is also a problem. The reason why large websites don't use PHP.

In addition, although PHP is powerful, its functions are relatively simple compared to other programming languages ​​and it is extremely dependent on third-party libraries. This means that when the library is restricted or problems arise, The PHP program cannot run normally, causing the website to be paralyzed and unable to be accessed normally.

Large websites like Baidu, Taobao, and Sina are mostly developed using high-performance languages ​​such as C, Java, and Python. These languages ​​have faster execution efficiency, strong scalability, and better maintainability. Features such as flexibility meet the needs of large websites.

Of course, this does not mean that PHP cannot handle the needs of large websites, but that for large websites, choosing a more suitable language can better adapt to the needs of the website. Therefore, the choice of language should not only consider the number of users, but more importantly, consider factors such as the size of the website, the number of visits, efficiency, etc., and comprehensively select a more suitable environment.

In conclusion, large websites do not necessarily not use PHP, but make different choices based on different needs. At the same time, when developing a website, technology selection should be made based on the scale and needs of the website, and the performance of the code should be continuously optimized and improved so that the website can run stably and quickly.
