PHP 分页功能
请问百度这个分页是怎么实现的?
回复讨论(解决方案)
这个问题问的有水平,我竟无言以对。。。
分页应该都差不多 百度也是传了一个参数 &pn=0
根据pn的值来判断当前是第几页 然后拿个脚印可以拿图片处理?之类的
如果你说的是1 2 3 4 5的显示的话
分页步骤
1.计算总条数
2.获取当前页
3.计算总页数 ceil(总条数/每页数量)
4.计算偏移量 就是limit n,m
5.查询数据 显示数据
注意:第三部你已经算出来总页数了 假设是10页
$str = ''; for($i=1;$i<=10;$i++){ str .= '<a href="#">'.$i.'</a>'; }echo $str;
这样12345的效果就出来了
然后再来点样式
a{ width:20px; height:20px; display:block; background:#ffffff; border:1px dashed #ccc; color:blue;}a:hover{ background:blue;}
马马虎虎 差不多了

假设当前页数是$page
$first_page = max($page - 5, 1);
$end_page = $first_page + 9;

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,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

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.
