Recently, pagination is required in the project. The paging function is often used. Therefore, it is encapsulated as a function.

// Paging/***** $ pageType paging type 1: Digital paging 2: Text paging * You can pass $ pageTotal, $ page, $ total, and other data as parameters, or use paging as a global variable (recommended) */function paging ($ pageType) {global $ pageTotal, $ page, $ total; if ($ pageType = 1) {echo'
'; Echo'
 
 

  
  
'; For ($ I = 0; $ I <$ pageTotal; $ I ++) {if ($ page = ($ I + 1) {echo'
  
  
. ($ I + 1). '"class =" selected ">'. ($ I + 1 ).'
';} Else {echo'
  
  
. ($ I + 1). '">'. ($ I + 1 ).'
';} Echo'
 
 
'; Echo'
';} Else if ($ pageType = 2) {echo'
'; Echo'
 
 

  
  
'; Echo'
  
  
'. $ Page.'/'. $ pageTotal.' page |
'; Echo'
  
  
Total'. $ Total .'Members |
'; // The first page if ($ page = 1) {echo'
  
  
Homepage |
'; Echo;} else {// $ _ SERVER ["SCRIPT_NAME"] Get the name of the current script to facilitate transplantation // You can also customize constants, constant Value and script file name are consistent echo'
  
  
. $ _ SERVER ["SCRIPT_NAME"]. '"> homepage |
'; Echo'
  
  
. $ _ SERVER ["SCRIPT_NAME"]. '? Page = '. ($ page-1).;} // The last page if ($ page = $ pageTotal) {echo; echo'
  
  
Last page |
';} Else {echo'
  
  
. $ _ SERVER ["SCRIPT_NAME"]. '? Page = '. ($ page + 1).; echo'
  
  
. $ _ SERVER ["SCRIPT_NAME"]. '? Page = '. ($ pageTotal).' "> last page |
';} Echo'
 
 
'; Echo'
';}}

Parameter description:

$ PageTotal indicates the total number of pages, $ page indicates the current page, and $ total indicates the total number of data retrieved from the database;

To simplify the process, encapsulate all parameters.

// Paging parameter package/*** $ SQL can be used to obtain the total number of data in an SQL statement * $ size the number of entries displayed on each page */function pageParam ($ SQL, $ size) {// set global variables for all involved parameters // $ where to start a page of pagestart // $ total number of records $ page a page $ total pageTotal pages global $ pagestart, $ pagesize, $ total, $ page, $ pageTotal; $ pagesize = $ size; // total number of Retrieved Data $ total = mysql_num_rows (queryDB ($ SQL); // error handling, first, determine whether there is an if (isset ($ _ GET ['page']) {// a specific page $ page = $ _ GET ['page']; // determine whether it is empty (0 is empty)/less than 0/whether it is a number if (empty ($ pag E) | $ page <0 |! Is_numeric ($ page) {$ page = 1;} else {$ page = intval ($ page); // integer, prevent decimal occurrence} else {// initialize display 1st page $ page = 1;} // CLEAR database if ($ total = 0) {// set to 1 $ pageTotal = 1;} total number of else {// pages (one-to-one integer) $ pageTotal = ceil ($ total/$ pagesize );} // The page number is greater than the total page number $ total if ($ page> $ pageTotal) {$ page = $ pageTotal ;} // when the page starts from a record $ pagestart = ($ page-1) * $ pagesize ;}

Parameter description:

$ Pagestart: When a page starts from a record, $ pagesize indicates the number of records displayed on each page.

In use, call pageParam first, and then call paging

/*** The first SQL statement that can obtain the total number of data * The number of entries displayed on the second page */pageParam ("select userid from user", 2 );

Select the call location based on the actual situation. The text page is as follows:

The number page is as follows:
