打造计数器DIY三步曲(下)
好多网站都提供了免费计数器服务,很久以前我就有个梦想,建立自己的免费计数器系统,而现在OSO提供了数据库,这一切将成为现实.
多数网站都是只向会员提供免费计数器的,我们也可以这样做,好让自己的网站也有上一些臣民,在他们注册的时候,可以自动生成一个ID,我们的计数器系统就全靠这个ID了!
当用户申请计数器时,首先当然是检查用户名和密码了,登陆成功后,从数据库中调出用户的ID出来,用户申请后系统自动创建两个文件countid.php和showid.php,简单流程可以如下:
$filea="count".$id."php";
$fileb="show".$id."php";
$fpa=fopen("count/$filea",w);
$fpb=fopen("show/$fileb",w)
然后写入文件,内容和中篇中的大同小异,只用将num改一下即可,简单流程可以如下:
fputs($fpa,$count,strlen($count));
fputs($fpb,$show,strlen($show));
$count=countid.php中的内容;
$show=showid.php中的内容;
这样就产生了countid.php和showid.php两个文件,同时让数据库insert num=id就可以了,最后返回一段代码,让用户知道怎样使用这个计数器,一切搞定!
不过我觉得申请计数器时可以让用户设置初值,数据库插入num时用replace来代替insert,这样用户如果忘了代码,随时可以重新申请一个,并设置好初值,而计数器会把原来的记录覆盖掉,这就没有必要让用户牢记代码,或者提供代码返回,这样太麻烦了!
怎么样?一切都很轻松吧,希望您能通过此三篇文章顺利地打造出自己的计数器系统,在此我预祝您能成功!

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.

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

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.
