[Ajax]简单的分页显示，
前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
<?PHP
header("content-type:text/html;charset=utf-8");
function showpages() {
$page=$_POST["page"];
if($page)
{
$MysqLi=new MysqLi('localhost','root','PHPdata');
if($MysqLi->connect_error)
{
die("连接失败");
}
$MysqLi->query("set names utf8");
$result=$MysqLi->query("select * from articles");
$total=$result->num_rows;
$start=($page-1)*10;
if($total-$start>0 and $total-$start<10)
{
$size=$total-$start;
}
else if($total-$start>=10)
{
$size=10;
}
else
{
$size=0;
}
if($size)
{
$result=$MysqLi->query("select * from articles limit $start,$size");
if($result->num_rows)
{
$json=array();
$index=0;
while($row=$result->fetch_row())
{
$json[$index][0]=$row[0];
$json[$index][1]=$row[1];
$index++;
}
$json=json_encode($json);
echo $json;
}
}
$MysqLi->close();
}
}
showpages();
?>
