Course Introduction:This article introduces the difference between const and define in PHP. I hope it will be helpful to students learning PHP. const is used to define class member variables. Once defined, its value cannot be changed; define defines global constants and can be accessed anywhere.

Course Introduction:Differences: 1. const is used for the definition of class member variables, while define cannot be used for the definition of class member variables; 2. const only accepts static scalars, while define can use any expression; 3. const is case-sensitive when defining constants , but define can specify whether it is case sensitive through the third parameter.

Course Introduction:The difference between PHP constants and variables: 1. Variables without defined keywords or functions are defined when assigning values, while constants must be defined using the "define()" function; 2. Variable names need to be modified with the dollar sign "$" , while constant names are not required.

Course Introduction:In PHP programming, constants and variables are what we often need to use, but there are very significant differences between them. This article will explore the differences between PHP constants and variables. 1.

In PHP, variables are declared using the $ symbol, followed by the variable name. The following are some characteristics of PHP variables: 1. Variables must start with the "$" symbol. 2. Variables can store any type of value, such as strings, numbers, arrays, etc.
