Why do most people like to use PHP to write websites?

ASP, .NET, PHP, and JSP are the most widely used programming languages ​​for websites now. What are the advantages and disadvantages of these languages? Let’s compare the four languages ​​first:

ASP: It is a background scripting language developed by Microsoft. Fast development, easy to use, and high efficiency are the advantages of ASP. However, in terms of security risks, ASP has the greatest hidden dangers among the four languages. Secondly, the limitations of the platform also limit the development of ASP.

.NET: Equivalent to an upgraded version of ASP, it provides a new programming model structure that can generate applications with better scalability and stability, and provide better security protection. But because it is a Microsoft product, the platform has limitations. There are also complex database links.

PHP: It is one of the current mainstream website development languages. The PHP source code is completely open. New function libraries are constantly being added and constantly updated, making PHP available on both UNIX and WIN platforms.
There are more new features. It provides rich functions, making it a better resource for programming. Platform independence and security are the biggest advantages of PHP. Of course, there are some small shortcomings, but as the most widely used back-end language, PHP's advantages still outweigh its shortcomings.

JSP: The JSP technology platform and server are independent of each other and are open source like PHP. JSP has been a very mature programming language since its emergence. It has integrated data source capabilities, is easy to maintain, and can effectively prevent system crashes and other advantages. There is no doubt that JSP is the best and most powerful of the four languages, but because its power determines the technical nature of its use, it is not the first choice for general corporate websites.

According to statistics, most people use PHP to write websites, so why is this? The specific reasons are as follows:

PHP is an HTML embedded language. It is a scripting language embedded in HTML documents that is executed on the server side. The style of the language is similar to C language. It is now used It is widely used by many website programmers.

PHP's unique syntax mixes C, Java, Perl and PHP's own innovative syntax. It can execute dynamic web pages faster than CGI or Perl. Compared with other programming languages, dynamic pages made with PHP embed the program into the HTML document for execution, and the execution efficiency is much higher than CGI that completely generates HTML tags; compared with the scripting language JavaScript, which is also embedded in the HTML document In contrast, PHP is executed on the server side, making full use of the server's performance; the PHP execution engine will also store PHP programs that users frequently access in memory, so other users do not need to recompile the program when they access the program again. Just execute the code in the memory directly, which is also one of the manifestations of PHP's high efficiency. PHP has very powerful functions. All CGI or JavaScript functions can be implemented by PHP, and it supports almost all popular databases and operating systems.
