It is similar to C and is a commonly used website programming language. PHP's unique syntax mixes C, Java, Perl, and PHP's own syntax. Conducive to learning, widely used, mainly applicable to the field of Web development. [1]

Since the development of the domestic Internet in the 1990s to the present, Internet information has covered almost all knowledge areas of our daily activities, and has gradually become an essential part of our lives, studies and work. According to statistics, since 2003, the size of China's web pages has basically maintained a doubling rate and is on the rise. As the most popular website program development language today, PHP language has the advantages of low cost, fast speed, good portability, built-in rich function libraries, etc., so it is used by more and more enterprises

- For very small projects, PHP is a very satisfying programming language. But for larger and more complex projects, PHP shows its weakness. Therefore, for a series of shortcomings exposed by PHP, we should continue to explore and then find solutions to certain problems. It's a good thing that an open source language is very popular. Hope all the problems can be solved one day, and then we will have an open source language, which is both open source and easy to use. [1]
