example, using three functions: Ob_start (), ob_get_contents (), Ob_end_clean ( )
Knowledge Points:
1, Ob_start function is generally used to open the cache, pay attention to the use of Ob_start can not have any output, such as spaces, characters and so on.
2, the Ob_get_contents function is mainly used to get the contents of the cache to return as a string, note that this function must be called before the Ob_end_clean function, otherwise the cached content is not obtained.
3, the Ob_end_clean function is mainly empty the contents of the cache and turn off the cache, success returns TRUE, Failure returns false

Parameter one: Static file, refers to the generated static file name, the file save path complete is: Static path/static file. For example, the static file settings A/index. Then the saved path is the project path/html/a/index.html (the default static path is not created in the Html folder of the project path)
