运行截图如下：
前端代码如下：
Student.php
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<h1>HelloWorld</h1>
<table border="1" cellspacing="1" cellpadding="1">
<thead>
<tr>
<td>ID</td>
<td>名字</td>
<td>年龄</td>
<td>性别</td>
<td>邮箱</td>
<td>地址</td>
<td>更新时间</td>
</tr>
</thead>
<tbody>
{foreach $students as $student}
<tr>
<td>{$student.id}</td>
<td>{$student.name}</td>
<td>{$student.age}</td>
<td>
{if $student.sex eq "m"} 男
{else}女
{/if}
</td>
<td>{$student.email}</td>
<td>{$student.address}</td>
<td>{$student.updateTime}</td>
</tr>
{/foreach}
</tbody>
</table>
<ul>
{$pageStr}
</ul>
</body>
</html>后端关键代码
提供数据的：
StudentController.php
<?php
namespace admin\controller;
use core\Controller;
use home\model\StudentModel;
use vendor\Page;
class StudentController extends Controller{
public function student(){
$page = $_REQUEST["page"] ?? 1;
$studentModel = new StudentModel();
$students = $studentModel->getAllStudents($page);
$counts = $studentModel->getCounts();
$cond = array("a" => A, "c" => C, "p" => P);
$pageStr = Page::clickPage(URL . "index.php", $counts, $cond, $page);
$this->assign("pageStr", $pageStr);
$this->assign("students", $students);
$this->assign("counts", $counts);
$this->display("student.html");
}
}分页代码：
Page.php
<?php
namespace vendor;
class Page{
public static function clickPage($url, $counts, $cond = array(), $page = 1, $pageCount = 5): string{
//所有页数
$pages = ceil($counts / $pageCount);
//上一页和下一页
$prev = $page > 1 ? $page - 1 : 1;
$next = $page < $pages ? $page + 1 : $pages;
//url上需要补充的内容
$patchInfo = "";
foreach ($cond as $key => $value){
$patchInfo .= $key . "=" . $value . "&";
}
//先展示上一页
$click = "<li><a href='{$url}?{$patchInfo}page={$prev}'>上一页</a></li>";
//如果总页数在7以内全都都展示出来
if($pages <= 7){
for($i = 1; $i <= $pages; $i++){
$click .= "<li><a href='{$url}?{$patchInfo}page={$i}'>{$i}</a></li>";
}
}
else{ //总页数在7页以上
//如果当前选中页数在5页以内，就把前7页全显示了。
if($page <= 5){
for($i = 1; $i <= 7; $i++){
$click .= "<li><a href='{$url}?{$patchInfo}page={$i}'>{$i}</a></li>";
}
$click .= "<li><a href='#'>...</a></li>";
}
else{
//如果当前选中的在第7页（包括第7页）以上，先展示1，2
$click .= "<li><a href='{$url}?{$patchInfo}page=1'>1</a></li>";
$click .= "<li><a href='{$url}?{$patchInfo}page=2'>2</a></li>";
$click .= "<li><a href='#'>...</a></li>";
//再展示中间页
//如果是最后3页了，就全部展示出来
if($pages - $page <= 3){
for($i = $pages - 4; $i <= $pages; $i++){
$click .= "<li><a href='{$url}?{$patchInfo}page={$i}'>{$i}</a></li>";
}
}
else{ //展示当前页面的前2页，和后2页
for($i = $page - 2; $i <= $page + 2; $i++){
$click .= "<li><a href='{$url}?{$patchInfo}page={$i}'>{$i}</a></li>";
}
$click .= "<li><a href='#'>...</a></li>";
}
}
}
//最后补一个下一页
$click .= "<li><a href='{$url}?{$patchInfo}page={$next}'>下一页</a></li>";
return $click;
}
}简单说下逻辑：
http://localhost:63343/IT1995Blog/public/index.php?a=student&c=Student&p=admin&page=2这个page就是当前页，程序里面写死了是每页5条，a=student，c=Student，p=admin是程序里面的逻辑，这个是必须要加的。所以在Page中会补这个。
