$total=mysql_num_rows($result);    //取得信息总数

PHP pagination code

Let me give you a class, it’s very simple,
//Paging function
class pg{
function genpage(&$sql,$page_size=2)
{
global $prepage,$nextpage,$pages,$sums; //out param
$page = $_GET["page"];
$eachpage = $page_size;
$ pagesql = strstr($sql," from ");
$pagesql = "select count(*) as ids ".$pagesql;
$result = mysql_query($pagesql) or die(mysql_error());
if($rs = mysql_fetch_array($result)) $sums = $rs[0];
$pages = ceil(($sums-0.5)/$eachpage)-1;
$pages = $pages>=0?$pages:0;
$prepage = ($page>0)?$page-1:0;
$nextpage = ($page<$pages)?$page+1: $pages;
$startpos = $page*$eachpage;
$sql .=" limit $startpos,$eachpage ";
}
function showpage()
{
global $page,$pages,$prepage,$nextpage,$queryString;
$queryString=$_SERVER['QUERY_STRING'];
if(preg_match("/page/",$queryString)){
$queryString=strstr($queryString,"&");
}else {
$queryString="&".$queryString;
}

$shownum =10/2;
$startpage = ($page>=$shownum)?$page-$shownum:0;
$endpage = ($page+$shownum<=$pages)?$page+$shownum:$pages;
$xs="";
$xs.="Total".($pages+1)."Pages: ";
if($page>0)$xs.= "Homepage";
if($startpage>0)
$xs.=" ... ?......The rest of the full text>>

PHP pagination code

include("connection.php");
$perNumber=10; //The number of records displayed on each page
$page=$_GET['page']; / /Get the current page value
$count=mysql_query("select count(*) from user"); //Get the total number of records
$rs=mysql_fetch_array($count);
$totalNumber=$rs [0];
$totalPage=ceil($totalNumber/$perNumber); //Calculate the total number of pages
if (!isset($page)) {
$page=1;
} //If there is no value, assign the value 1
$startCount=($page-1)*$perNumber; //Paging starts, calculate the starting record according to this method
$result=mysql_query("select * from user limit $startCount,$perNumber"); //Calculate the starting record and number of records based on the previous calculation
while ($row=mysql_fetch_array($result)) {
echo "user_id:".$row [0]."
";
echo "username:".$row[1]."
"; //Display the contents of the database
}
if ($page != 1) { //The number of pages is not equal to 1
?>
Up One page
}
for ($i=1;$i<=$totalPage;$i++ ) { //Loop through the page
?>

}
if ($page<$totalPage) { //If page is less than the total number of pages, display the next page link
? >
Next page
}
?>
