Function code solving

Function code solving function multi ($ num, $ perpage, $ curpage, $ mpurl, $ maxpages = 0, $ page = 10, $ autogoto = FALSE, $ simple = FALSE, $ jsfunc = FALSE)
{
Return $ num> $ perpage? Helper_page: multi ($ num, $ perpage, $ curpage, $ mpurl, $ maxpages, $ page, $ autogoto, $ simple, $ jsfunc ):'';
}
Please explain in detail the significance of the previous function code. thank you!

Use of discuz paging function multi
The multi function in the function_core file is a paging function. the prototype is as follows:
Multi ($ num, $ perpage, $ curpage, $ mpurl, $ maxpages = 0, $ page = 10, $ autogoto = FALSE, $ simple = FALSE)
Where
$ Num total number of records,
$ Perpage: number of records displayed on each page,
$ Number of current curpage pages,
$ Mpurl: The URL of the page. if the url contains "? ", Followed by" & page = 3 "(3 is the number of page numbers), does not exist"?" Add "? Page = 4 "(4 is the number of page numbers ),
$ Maxpages = 0-position parameter,
$ Page = 10 displays several pages each time.
Other parameters can be left empty.
