In recent years, with the rapid development of the Internet and the widespread application of cloud computing technology, website development languages ​​​​have derived from ASP and JSP in the past and a series of emerging languages ​​​​such as PHP, Python, and Ruby. Although these languages ​​​​have their own advantages and disadvantages, PHP has developed into one of the most popular website development languages ​​and is widely used in the construction of various websites and the development of web pages. But many people are confused that PHP is slower than ASP. What is going on? Next, let's explore why PHP calls are not as fast as ASP.

Different frequency of use

First of all, we need to realize that the application scenarios of the two website development languages ​​​​of PHP and ASP are different. ASP is a dynamic website application development technology developed by Microsoft for the Windows platform, while PHP is a language based on Open Source and can run on all mainstream operating systems, including Windows, Linux, Unix, etc. In Windows systems, ASP can often have extremely excellent performance because it and IIS (Internet Information Server) complement each other. However, once it crosses over to other operating system platforms, ASP's performance will be greatly reduced because IIS cannot be well integrated into other operating systems. In contrast, PHP has the advantage of being cross-platform and can be easily run on different operating systems. Due to its excellent open source community support, it is constantly being improved and optimized, so it has been widely used in the field of web development. application.

Different operating mechanism

The operating mechanism of PHP is very different from that of ASP. In PHP, the code is interpreted and run, which means that the source code must be interpreted every time PHP is run. ASP needs to be compiled before running. It can be understood that the ASP program needs to be compiled into a binary file before being executed. In this case, in some performance-sensitive situations, ASP's performance will be relatively high. In PHP, due to its interpretation and running characteristics, it needs to be reinterpreted every time, which consumes some performance.

Different application scenarios

In addition to the above two reasons, the burden, pressure and workload of PHP and ASP in actual applications are also different. For example, ASP uses a large number of COM components, which need to be read from the server, which increases the burden of network transmission. PHP uses a lightweight parser to reduce the load and make it better adaptable to large-scale website applications.

Furthermore, because ASP is interspersed with a large amount of program logic and HTML forms, its code has poor readability and maintainability when multiple people collaborate on programming. PHP adopts the MVC model to completely separate program logic and HTML, making the code clearer and clearer, thus improving the readability and maintainability of the code.

To sum up, the reason why PHP calls are not as fast as ASP is actually caused by the differences in the operating mechanism, usage frequency and application scenarios of the two languages. We cannot look at this problem from just one angle. Only by in-depth analysis and understanding of the essential differences between the two languages ​​can we better leverage their advantages and achieve better results in actual development.
