这篇文章给大家介绍的文章内容是关于php分页和正则验证的代码实现,有很好的参考价值,希望可以帮助到有需要的朋友。

分页:

<?php
header("Content-type:text/html;Charset=utf8");

$link=mysqli_connect("localhost:3306","root","root","weektwo");
if(!$link) echo "连接失败的原因是:" . mysqli_connect_error();
mysqli_query($link,"set names utf8");
   $tiao=4;
   $sql="select count(*) from kao";
   $res=mysqli_query($link,$sql);
   $zong=mysqli_fetch_assoc($res);
   $z=count($zong);
   $max=ceil($z/$tiao);
if(!$_GET['page']){
       $page=1;
}else{

     if($page<1){
      $page=1;
     }elseif($page>$max){
      $page=$max;

     }else{

      $page=$_GET['page'];
     }

}
$ye=($page-1)*$tiao;
$sql="select * from kao where limit ".$ye.",".$tiao;
$a=mysqli_query($link,$sql);

while($res=mysqli_fetch_assoc($a)){
     $arr[]=$res;
}

// var_dump($arr);die;
?>
