Php paging extension code

The url-based parameter passing method may have a certain impact or a known bug. this time, we made some extensions and were compatible with the previous mode that originally published a paging class out of the database, recently, I found that sometimes when the search is too large, the url-based parameter passing method may have a certain impact or a known bug. this time, I made some extensions, at the same time, it is compatible with the previous mode. the above is simple. you only need to set one more parameter and the code is as follows:
The code is as follows:
/**
* Function: Paging class, based on the total amount of data provided and page size
* Creation Date: Fri Apr 20 16:45:21 CST 2007
