PHP Paging Code

I'll give you a class, it's simple,
Paging functions
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). " Page: ";
if ($page >0) $xs. = "Home </a>";
if ($startpage >0)
$xs. = "...? </a> Remaining full text >>

PHP Paging Code

Include ("connection.php");
$perNumber = 10; The number of records displayed per page
$page =$_get[' page '; Get the current page value
$count =mysql_query ("SELECT count (*) from user"); Total Records obtained
$rs =mysql_fetch_array ($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 a value of 1
$startCount = ($page-1) * $PERNUMBER; Start with pagination and calculate the starting record based on this method
$result =mysql_query ("SELECT * from User limit $startCount, $perNumber"); Based on the previous calculation, the number of records and records started
while ($row =mysql_fetch_array ($result)) {
echo "user_id:". $row [0]. "
";
echo "Username:". $row [1]. "
"; Displaying the contents of a database
}
if ($page! = 1) {//pages not equal to 1
?>
"> Prev </a>
}
for ($i =1; $i <= $totalPage; $i + +) {//Cycle Show page
?>
"> </a>
}
if ($page < $totalPage) {//If page is less than total pages, show next link
?>
"> Next </a>
}
?>
