PHP to solve the old system to detect all data paging class _php instance

Added several custom methods for extracting the specified fragment from the MySQL result set, and the reason for not invoking the release is that this involves the original checksum of the program
Thanks to the help of the great God on the Internet .... The old system kills people, they can't move backstage.

Copy Code code as follows:
