Free guestbook About the paging code of the text guestbook

//When writing a file, use "|||" to separate each record, and "||" to separate each field in the record
//For example, record one is represented as $str1=$name." ||".$pass."||".$title."||".$message."||".…………
//Then use when connecting record one and record two, $str=$str1. "|||".$str2."|||.………
//The final generated file is as follows

The above introduces the paging code of the free guestbook and the text guestbook, including the content of the free guestbook. I hope it will be helpful to friends who are interested in PHP tutorials.
