The difference between include and require in PHP

1. The order of loading is different: the Require is loaded and then executed, and the include is executed to this statement before loading;
2. The level at which the error is raised is different: require throws a fatal error if it is loaded, causing the subsequent statement to no longer execute, and the include only throws warning, without affecting the execution of the subsequent statement
3. Conditional load support: Require cannot determine whether the load is loaded by the condition, as long as there is a certain load, and the include can be judged by the condition to load
