本文實(shí)例講述了php實(shí)現(xiàn)的后臺(tái)表格分頁(yè)功能。分享給大家供大家參考，具體如下：
?php
//init.php
$conn = mysqli_connect('127.0.0.1','root','','xz',3306);
$sql = "SET NAMES UTF8";
mysqli_query($conn,$sql);
$pagecount = 3;
?>
user.php：
?php
//用戶(hù)管理
echo "用戶(hù)管理br/>";
@$start = $_REQUEST['start'];
if($start === null || $start === " "){
die("start required");
}
require("init.php");
$sql = "SELECT * FROM xz_user LIMIT $start,$pagecount";
$sql1 = "SELECT uid FROM xz_user";
$result = mysqli_query($conn,$sql);
$result1 = mysqli_query($conn,$sql1);
if($result === false || $result1 === false) {
echo "執(zhí)行失敗";
}else {
//$rowcount = mysqli_affected_rows($conn);
$arr = mysqli_fetch_all($result,1);
$rowcount = count($arr);
echo "查詢(xún)到的結(jié)果行數(shù)：" . $rowcount . "br/>";
//if($rowcount > 0){
$arr1 = mysqli_fetch_all($result1,1);
$count = count($arr1);
echo "總行數(shù)：$countbr/>";
?>

注：
（1）用AJAX可以實(shí)現(xiàn)傳值優(yōu)化，提升性能，這里沒(méi)有實(shí)現(xiàn)；
（2）下一頁(yè)那邊還沒(méi)有一些bug，不能到最后一頁(yè)停止，后續(xù)再實(shí)現(xiàn)吧。
