PHP MSSQL paging example_php skills
The example in this article shares with you a PHP MSSQL refreshable paging example. The specific content is as follows
<?php
/*
'页面说明：
*/
$link=mssql_connect("MYSQL2005","sa","123456") or die("db link error!".mssql_error());
mssql_select_db("edu_dzk",$link) or die("db open error!".mssql_error());
//mssql_query("set names 'utf8'");
$sqlstrcount="SELECT count(1) FROM reguser";
$page = $_GET["page"];
if(!is_numeric($page)){
$page="1";
}
$pagesize="30";
//$sql=mysql_query($sqlstr);
//$totalnum=mysql_num_rows($sql);
$sql=mssql_query($sqlstrcount);
list($totalnum)=mssql_fetch_row($sql);
$pagecount=ceil($totalnum/$pagesize);
$offset=($page-1)*$pagesize;
$sqlstr="Select top ".($pagesize)." * from reguser where id not in (select top ".(($page-1)*$pagesize)." id from reguser order by id desc) order by id desc";
$sql=mssql_query($sqlstr);
$result="";
while($result=mssql_fetch_array($sql)){
echo $result["id"].'<br>';
}
showpageinfo2($totalnum,$pagecount,$page,"&z=".$z);
mssql_Close($link);
function showpageinfo2($totalnum,$pagecount,$page,$filster)
{
echo "共计: $totalnum 条记录,共 $pagecount 页,当前是第 $page 页 ";
if($page!=1)
{
echo "<a href=?page=1$filster>首页</a> ";
echo "<a href=?page=".($page-1)."$filster>上一页</a> ";
}
if($page<$pagecount)
{
echo "<a href=?page=".($page+1)."$filster>下一页</a> ";
echo "<a href=?page=$pagecount$filster>尾页</a> ";
}
}
?>
The PHP MSSQL general paging formula is shared below for your reference. The specific content is as follows
<?php
//phpinfo();
//$conn=mssql_connect('192.168.0.3','app','web')or die (mssql_get_last_message());
//if($conn)
//{
//?echo "success";
//}else{
//?echo "fail";
//}
?>
<html>
<head>
<title>PHP分页</title>
</head>
<body>
<?
$gPageSize= 10; //每页显示的记录数
$hostname = "."; //MsSQL Server
$dbuser = "sa"; //用户名
$dbpasswd = ""; //密码
//连接数据库
$id = mssql_connect($hostname,$dbuser,$dbpasswd) or die("无法连接数据库服务器！");
$db = mssql_select_db("phmis04",$id) or die("无法连接数据库！");
//以xxx表为例,构建查询字符串
$query = "select top 20 ag_mate,ag_color,ag_width,ag_mode,mi_name,convert(char,ag_date,23)as ag_date,ag_grid,au_name,ag_num from acco_grid join mate_info on ag_mate=mi_id join appl_unit on au_id=ag_unit;";
//执行查询语句
$rresult = mssql_query($query) or die("无法执行SQL：$query");
//$page变量标示当前显示的页
if(!isset($page)) $page=1;
if($page==0) $page=1;
//得到当前查询到的纪录数 $nNumRows
if(($nNumRows= mssql_num_rows($rresult))<=0)
{
echo "<p align=center>没有纪录";
exit;
};
//得到最大页码数MaxPage
$MaxPage = (int)ceil($nNumRows/$gPageSize);
if((int)$page > $MaxPage)
$page=$maxPage;

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
