PHP implements paging code
This article mainly introduces the PHP paging code, which has certain reference value. Now I share it with you. Friends in need can refer to it.
<?php header("content-type:text/html;charset=utf8"); include 'conn.php'; //每页显示的数据条数 $pageSise = 2; $result = $conn->query("select * from message "); //数据总条数 $totalNum = $result->num_rows; //总页数 $totalPageCount = ceil($totalNum/$pageSise); //判断当前是哪一页 $nowPage = isset($_GET['page']) ? intval($_GET['page']) : 1; //上一页 $prev = ($nowPage - 1 <=0)? 1 : $nowPage-1; //下一页 $next = ($nowPage+1>=$totalPageCount) ? $totalPageCount : $nowPage +1; //如果传入的页数大于总页数,则重新给nowpage赋值 if($nowPage>$totalPageCount || $nowPage == 0){ // echo "error:can not found the page<br>"; $nowPage = $totalPageCount; } //偏移量 $offset = ($nowPage -1)*$pageSise; //sql语句 $sql = "select * from message limit $offset,$pageSise"; $result2 = $conn->query($sql); //输出页面内容 while($row = $result2->fetch_assoc()){ echo $row['user'].'|'.$row['title'].'<br>'; } ?> <!--分页开始,首先写好分页html和css--> <link href="//cdn.bootcss.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"> <script src="//cdn.bootcss.com/jquery/2.1.1/jquery.min.js"></script> <script src="//cdn.bootcss.com/bootstrap/3.3.6/js/bootstrap.min.js"></script> <ul class="pagination"> <?php echo "<li><a href='".$_SERVER['PHP_SELF']."?page=1'>首页</a></li>"; echo "<li><a href='".$_SERVER['PHP_SELF']."?page=".$prev."'>«</a></li>"; ?> <?php $page = 5; for($a=1;$a<=$page;$a++){ echo "<li><a href='".$_SERVER['PHP_SELF']."?page=".$a."'>$a</a></li>"; } ?> <?php echo "<li><a href='".$_SERVER['PHP_SELF']."?page=".$next."'>»</a></li>"; echo " <li><a href='".$_SERVER['PHP_SELF']."?page=".$totalPageCount."'>尾页</a></li>"; ?> </ul>

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,

Article discusses late static binding (LSB) in PHP, introduced in PHP 5.3, allowing runtime resolution of static method calls for more flexible inheritance.Main issue: LSB vs. traditional polymorphism; LSB's practical applications and potential perfo

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
