本文實例講述了php實現(xiàn)的后臺表格分頁功能。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);
$pagecount = 3;
?>
user.php：
?php
//用戶管理
echo "用戶管理br/>";
@$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)：$countbr/>";
?>
table border="1">
tr>
td>用戶編號/td>
td>用戶名/td>
td>密碼/td>
td>郵箱/td>
td>電話/td>
td>操作/td>
/tr>
?php
for($i=0;$icount($arr);$i++){
$tmp = $arr[$i]['uid'];
echo "
tr>
td>".$arr[$i]['uid']."/td>
td>".$arr[$i]['uname']."/td>
td>".$arr[$i]['upwd']."/td>
td>".$arr[$i]['email']."/td>
td>".$arr[$i]['phone']."/td>
td>a href='delete.php?uid=".$tmp."'>刪除/a>/td>
/tr>
";
}
?>
/table>
?php
}
?>

delete.php：
?php
//刪除用戶
echo "刪除用戶br/>";
@$uid = $_REQUEST['uid'];
if($uid === null || $uid === " "){ //這里注意，是||
die("uid required");
}
require('init.php');
$sql = "DELETE FROM xz_user WHERE uid='$uid'";
$sql1 = "UPDATE xz_user SET uid=uid-1 WHERE uid > '$uid'";
$result = mysqli_query($conn,$sql);
if($result === false){
echo "執(zhí)行失敗";
}else{
$count = mysqli_affected_rows($conn);
if($count > 0){
echo "用戶刪除成功";
$result1= mysqli_query($conn,$sql1);
if($result1 === false){
echo "重排序失敗";
}else{
echo "重排序成功";
}
if($uid % $pagecount == 0)
Header("Location:user.php?start=$uid");
if($uid % $pagecount == 1){
$uid -= 1;
Header("Location:user.php?start=$uid");
}
if($uid % $pagecount == 2){
$uid -= 2;
Header("Location:user.php?start=$uid");
}
}else{
echo "要刪除的用戶不存在";
}
}
?>
注：
（1）用AJAX可以實現(xiàn)傳值優(yōu)化，提升性能，這里沒有實現(xiàn)；
（2）下一頁那邊還沒有一些bug，不能到最后一頁停止，后續(xù)再實現(xiàn)吧。
