The array learning series articles I have written so far are all here. I will update when there are new articles!
By the way, let me introduce PHP arrays to you:
Arrays are one of the means to effectively organize and manage large amounts of data. Through the powerful function of arrays, a large amount of data of the same nature can be stored. , sorting, insertion and deletion operations, which can effectively improve program development efficiency and improve the way programs are written.
PHP is one of the most popular Web development languages on the market. With its open source code and fast upgrade speed, it has more powerful ability to operate arrays. In particular, PHP provides a lot of convenience for program developers. , the easy-to-understand array operation functions make PHP popular among the majority of Web developers.
