模仿百度搜索结果的分页导航.
<code><?php header('Content-Type: text/html;charset=utf-8'); $page = (!empty($_GET['p'])) ? intval($_GET['p']) : 1; page($page); function page($page=1, $page_size=10){ $total_records = 505; $total_pagas = ceil($total_records/$page_size); echo '页数: '.$total_pagas.'<br />'; if($total_pagas==0){ echo '<b>查询结果为空</b><br>'; }else if($page>$total_pagas || $page <a href="page.php?p=1">最前</a><br> <a href="page.php?p=<?php%20echo%20%24total_pagas;%20?>">最后</a><br> <?php echo '<b>第1页(没有该页,统一显示第一页)<br>'; $page = 1; if($total_pagas>=$page+4){ for($i=$page+1;$i <a href="page.php?p=<?php%20echo%20%24i;%20?>">第<?php echo $i; ?>页</a><br> <?php } if($page!=$total_pagas){ ?> <a href="page.php?p=<?php%20echo%20%24page+1;%20?>">下一页</a><br> <?php } }else{ for($i=$page+1;$i<=$total_pagas;$i++){ //echo $i; ?> <a href="page.php?p=<?php%20echo%20%24i;%20?>">第<?php echo $i; ?>页</a><br> <?php } if($page!=$total_pagas){ ?> <a href="page.php?p=<?php%20echo%20%24page+1;%20?>">下一页</a><br> <?php } } }else{ ?> <a href="page.php?p=1">最前</a><br> <a href="page.php?p=<?php%20echo%20%24total_pagas;%20?>">最后</a><br> <?php //前输出5页,后输出4页. if($page<=5){ if($page!=1){ ?> <a href="page.php?p=<?php%20echo%20%24page-1;%20?>">上一页</a><br> <?php } for($i=1;$i<$page;$i++){ //echo $i; ?> <a href="page.php?p=<?php%20echo%20%24i;%20?>">第<?php echo $i; ?>页</a><br> <?php } }else{ if($page!=1){ ?> <a href="page.php?p=<?php%20echo%20%24page-1;%20?>">上一页</a><br> <?php } for($i=$page-5;$i<$page;$i++){ //echo $i; ?> <a href="page.php?p=<?php%20echo%20%24i;%20?>">第<?php echo $i; ?>页</a><br> <?php } } echo '<b>第'.$page.'页(当前页)<br>'; if($total_pagas>=$page+4){ for($i=$page+1;$i <a href="page.php?p=<?php%20echo%20%24i;%20?>">第<?php echo $i; ?>页</a><br> <?php } if($page!=$total_pagas){ ?> <a href="page.php?p=<?php%20echo%20%24page+1;%20?>">下一页</a><br> <?php } }else{ for($i=$page+1;$i<=$total_pagas;$i++){ //echo $i; ?> <a href="page.php?p=<?php%20echo%20%24i;%20?>">第<?php echo $i; ?>页</a><br> <?php } if($page!=$total_pagas){ ?> <a href="page.php?p=<?php%20echo%20%24page+1;%20?>">下一页</a><br> <?php } } } } ?></code>
<code><?php $page = $_GET['pages']; //第几页 $page_num = 10; 设置每页显示条数 /* 不知道你的api都有什么参数,我模拟个通用的分页api函数吧; 通常传递两个参数就可以了 一个是起始位置,一个是显示条数 起始位置 = 第几页 * 每页显示条数 显示条数为你的自定义条数 */ $page_mes = pagination($page * $page_num, $page_num); //pagination分页接口方法 foreach($page_mes as $key => $val){ //分页数据显示 } ?></code>
大概就是这样的...

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
