Article Introduction：PHP is a very popular web development language that comes with many powerful functions, making our development more efficient and simpler. Among them, the data classification function of PHP function can help us classify and process the given data, making development more convenient. In this article, we will take a closer look at the usage and examples of these functions. 1. Introduction to data classification functions In PHP, there are many built-in functions that can help us process data, including data classification functions. This type of function can transform the given data into some

Article Introduction：PHP functions can be divided into: 1. Variable functions. During execution, the PHP script will look for a function with the same name as the value of the variable and execute it; 2. Recursive functions, which will call itself during the execution of the function; 3. Custom functions, PHP Provides us with a huge function library for us to use.

Article Introduction：Classification of Numbers, 55:55-Classification of Functions: 55-Classification of Functions A function is a block of code that can be executed whenever needed. It includes not only user-defined functions, but also library functions implemented in programming languages. A user-defined function looks like the following pseudocode in the manual showing the purpose of the function: function foo($arg_1, $arg_2, ..., $arg_n) {echo "Example function.n";return $retval; } Any valid PHP code can be written inside functions, even packages

Article Introduction：PHP Mall Function Tutorial: Implementing Product Classification and Filtering Functions When developing a PHP mall project, product classification and filtering functions are essential. Through reasonable classification and filtering, users can easily find and purchase products. This article will introduce in detail how to use PHP to implement product classification and filtering functions, and attach code examples. To create a product classification, first, we need to create a product classification table and corresponding model class. The product classification table must contain at least the following fields: id, name, parent_id. Among them, id is self-increasing

Article Introduction：PHP functions are divided into three major categories: core functions (built-in into the language, no extension required), extension functions (added through extensions, such as PDO), and user-defined functions (created by developers). Understanding these classifications is essential for efficient PHP programming, such as using the PDO extension to connect to a MySQL database.
