Include ("Connect.rec");

$QH =mysql_query ("Select COUNT (*) as rcnt from Guestbook");

$data =mysql_fetch_array ($QH);

$NR = $data ["rcnt"];

Determines whether the offset parameter is passed to the script, and if not, uses the default value of 0

if (empty ($offset))

{

$offset = 0;

}
Query results (Here are 20 per page, but you can completely change it yourself)

$result =mysql_query ("SELECT * from Guestbook ORDER BY time Desc LIMIT $offset, 5");
$result =mysql_query ("SELECT * from Guestbook LIMIT $offset, 5");

Shows the 5 records returned

while ($data =mysql_fetch_array ($result))
{
printf ("Name:%s
", $data [" name "]);
printf ("email:%s
", $data [" Mail "]);
printf ("Personal page:%s
", $data [" url "]);
printf ("From:%s
", $data [" IP "]);
printf ("Message Time:%s
", $data [" Time "]);
printf ("Subject:%s
", $data [" title "]);
printf ("Content:%s
", $data [" ly "]);
printf (" ");
}

Next, write a link to another page

if ($offset)//If the offset is 0, the previous page link is not displayed
{
$preoffset = $offset-5;
Print "previous page n";
}

Calculate the total number of pages required

$pages =ceil ($NR/5); $pages variable now contains the required number of pages

for ($i =1; $i <= $pages; $i + +)

{

$newoffset =5* $i-5;

print "$i n";

}

Check if it is the last page
$next = $offset +5;
if ($next < $NR)
{
Print "next page n";
}
printf ("Back")
?>
